Not if he cut the neutral or ground.
Open up the hole and see what he did.

Of course, if he had hit either the neutral or the ground, that wouldn't
affect the voltages on the hot legs...

I agree. Instead of all this theory, he should look where changes
were made.
I ddin't undderstand the story about the electrician, but drilling
without seeing where the drill will come out sounds, I don't know,
risky?

I've seen it happen myself - putting in the mounts for a new TV in the
C&POs mess; the shipwright doing the mounting measured twice and for
safety's sake put a block of 2x4 between the wireway and the bulkhead -
but the block shifted and the drill went as neatly as you please into
the lighting circuit for that WT compartment. No lightshow, just the
lights went out.
We razzed him about it for weeks afterwards...
