That's a possibility.

And again the odd thing about it is that guy #1 was
able to dial in the negative thrust angle I requested(my
Accord has a leftward drift, more noticeable on highways)
that cannot be explained by my alignment results, nor by
any bent parts, dragging brakes, unequal tire pressures, etc.

So the negative thrust angle counters that, and I'm not always
having to nudge the steering wheel rightward to stay out of the
lane to my left!

Now all I need is a touch - juat a bit - of front Toe-in, but still
within Honda Specs. Alignment guy #2 says "no problem".
