The Perl regular expression engine starts the next match always after the last matched character of the previous match. So you will need lookahead assertions (?= that don't adjust pos if you don't want to fiddle with pos yourself (see perlre on lookahead assertions):

perl -le "$_='1234';@x=/(?=(\d\d))/g;print for @x"
