"The reason neutral wires are called that is because they are tied

ground" seems to me to be incorrect. True, in US wiring, neutral
wires
usually have near-ground voltages on them, but more generally a
neutral
wire is one with no current flowing in it when a system is in
balance.
In US wiring the neutral does have current running through it.

The neutral is the center tap of the pole transformer, and the return
for 120V loads. If you pull 50A from one hot leg and 40A from the
other, the 10A difference will flow back on the neutral.

A voltmeter tells you nothing about currents, you need a clamp-on
ammeter to measure them.
