japhy took a look at this but I guess he didn't post about it yet. Basically, loops and repeated statements are not interchangeable - they're compiled differently. He suggested running the following two tests, which are quite enlightening: 
 perl -MO=Terse -e '/x/; /x/;'

 perl -MO=Terse -e '/x/ for 1, 2'
