Would it cause any problem to omit vertical joint mortar in the inner
leaf of a bathroom wall? I think the answer would be no, and I see a
possible reason to do it.

What's the reason?

Yes

You will get air through the joint, which will mean a loss of heat,
when compared to a mortared joint.

I'm not too sure about that.

The reason is to increase damp evaporation from the plaster and inner
wall leaf into the cavity. Missing verttical joints provides more
evaporation area plus the damp can evap direct from the plaster or PB,
doesnt need to travel through the brick/block first. Damp is a common
issue in UK bathrooms, shower tilework sometimes leaks etc.

So the water condences on the outside of the inside leaf, and runs
down the cavity - not so clever I think.

If you are worried about tiles leaking, there are many products that
you use to put a waterproof layer where the plaster woild be.

Why do you think that would happen?

By not having a proper thermal barrier behind the plaster,
you are far more likely to create cold spots and condensation.
