I didn't mind either way. When we spoke, I was making a general comment that descriptive names are generally good but short, non-descriptive names aren't always bad. The obvious example is 'i', and 'j' for loop counters. Personally, I use TmpReg for trivial scratch registers and use more descriptive names when there are several of them (otherwise it starts to get confusing).
