The problem is that you've defined "scrolling command" to mean something that has nothing to do with scrolling (i.e., commands which MOST DEFINITELY DON'T exit isearch).  This leads to ridiculous conclusions such as "C-u `universal-argument' is a scrolling command in its
own right."

Awkward phrasing, but if you read Drew's post it's fairly clear what he meant:  `C-u' "passes through" if it passes a prefix argument to the next command (its normal purpose) without exiting isearch.  So, a command "passes through" if it also works normally without exiting isearch.
