it is the list context in the   @t1 = ... m//g   which gives you multiple results for just that single match. I does, however, not create a loop.

That's why it doesn't work in your while loop.   $1   and   $2   get filled only once, because without the list context, that's what the matching operator   m   does in those cases.

 Update: Wrong thought, obviously.
