in what sense of the word "worked" does it work?  it most
certainly DOES NOT work.  you seem to have a fundamental
misunderstanding of the difference between & and &&.
& is not any kind of a short-circuit operator, while && is:

$ perl -le '0 && print "howdy!"'
$ perl -le '0 & print "howdy!"' 
howdy!

how are you defining "work"?  this produces identical output
of the original solution (with the minor difference that the
original solution didn't print 'aaaa').
