Great question!

You’re basically right — you want to use a loading meter because you want to see how that voltage will act when a load is applied to it.

In fact, you should essentially always use a loading meter (or the LoZ function on a multimeter) when measuring AC voltage. It keeps you from getting tricked by things like open neutrals and ghost voltage, and it shows you when a circuit fails under load, like when you have a loose connection.
