IIRC, it's up to the shell to decide job execution order.  So, at a
guess, I'd reckon that bash has some `optimal' method of execution.
Or maybe you're just getting different results after just one (or a
small number of) test(s)?  [You did do it more than once, right?  :)]

ObDisclaimer:  I'm drawing a long bow here---I don't have Stevens
here to refer to, but I do recall a larg(ish) section in same
pointing out such subtle differences in job execution.  But, no-one
else has responded yet, so...
