How Old School C Programmers Process Arguments

Maybe I've forgotten more C than I'd like to admit,

  while (--argc > 0 && (*++argv)[0] == '-')

  ...
  Notice that the decrement always occurs before the ‘>’ is 
  evaluated. This would be true even if it were postfix (i.e., argc-- > 0).

but isn't the last statement ("This would be true even if...") in error? IIRC a post-decrement would occur after the ‘>’ is evaluated.

edit: clarity

The decrement is the same either way, the value yielded by the decrement expression would however be different. I don't like the wording either.
