My guess - eor (^) was quicker than not-equal (!=) on a PDP-11.
That code fragment for checking uid's has been around a -long-
time, if my memory serves me.
It's gotten to be like the infamous "!!" boolean conversion
operator, a bit of vernacular that would be harder to read if
recoded using modern coding style.
