I've never understood why this 'alternative' method isn't more popular.
The Wikipedia article says it "can cause confusion" but, come on, it's
only wires and switches - you don't need a PhD to understand it!

For UK wiring in twin- and triple-&-earth cable the alternative method
(as it used to be called) *is* standard. A 'switch-drop' T&E cable from
a ceiling rose or luminaire goes to one 2-way switch. From that switch
you run 3&E cable via zero or more intermediate switches to a second
2-way switch.

The other method (formerly called standard) is appropriate when wiring
with singles in conduit.
