Nonsense it shows it by the TV and protecting the TV in fig 7.
In fig 8, it clearly shows two TV's. One uses a plug-in multi-port
surge protector and it's protected from the destructive surge.
The other TV, TV2 without a plug-in protector in the same diagram
is damaged by the surge. The IEEE guide then states:

It protects TV1 by earthing the surge 8000 volts destructively via TV2. If you need a power strip protector on TV2, then you need one on every appliance including every clock, furnace, dishwasher, clock radio, etc. How do you put a protector on each GFCI? Why would anyone spend over $2500 on plug-in protectors when one 'whole house' protector does more for only $1 per protected appliance? Because naysayers who never did this stuff recommend the scam.

So you advocate 8000 volts inside a building as acceptable? Why is that type of transient never acceptable in any facility that cannot have damage? It is called hearsay. Many automatically believe hearsay without any doubts, questions, or a demand for how it works. Protection is always about a surge current earthed outside the building. So that 8000 volts is not hunting for earth destructively via any appliance. For superior protection that costs tens or 100 times less money.

Plug-in protectors do virtually no protection from typically destructive surges. They are for another surge that typically does no damage. Plug-in protectors are implemented only after a 'whole house' protector is installed (by people who actually do this stuff). Plug-in protectors even need to be protected by a 'whole house' protector. Since fire is another outgoing problem with those undersized and high profit SPDs.

The IEEE Guide says what effective protectors must do:
2.2 Surge Protective Device Ratings
There are three requirements of the service entrance SPD. They
are as follows:
1) To suppress the larger surges from the outside environment
to levels that would not be damaging to equipment at the
service entrance, or to equipment (air conditioning, wired-in
appliances) directly connected to the branch circuits.
2) To reduce the surge current to the downstream SPDs
(including multiport SPDs).
3) To stop the large lightning currents from passing into
the house wiring system and damaging the wiring or inducing
large voltages that would damage electronic equipment.

That is what effective surge protection does. That is never accomplished with any plug-in protector. Attacking the messenger may convince the naive. But it does not prove a power strip does any protection from a typically destructive surge.

Then the Guide says what effective protectors do and what a power strip protector never does:
2.3.1 Grounding
An effective, low-impedance ground path is critical
for the successful operation of an SPD. High surge
currents impinging on a power distribution system
having a relatively high grounding resistance can
create enormous ground potential rises(see Section
4 beginning on page 30), resulting in damage.
Therefore, an evaluation of the service entrance
grounding system at the time of the SPD
installation is very important.

What do you ignore because you never did this stuff? Earth ground. Those educated by advertising never discuss the most important component in every protection system: single point earth ground.

A protector (SPD) is only as effective as its earth ground. Intentionally ignoring IEEE Guide paragraphs that you do not understand does not prove you have higher intelligence. Attacking the messenger while ignoring what the Guide really says you are easily manipulated by sales myths.

The IEEE Guide says things you ignore to remain deceived. The only solution used in every facility that cannot have damage is earthing. With low impedance (another phrase you intentionally ignore) connection to that ground via a wire or 'whole house' protector. Some facilities ban power strip protectors due to a fire risk and other problems. And because a properly earthed 'whole house' solution does over 99.5% of the protection.
