I looked, but perlsyn is big.  I looked harder and found it.

       The LABEL [on a while loop] identifies the loop for the 
       loop control statements "next", "last", and "redo".  If 
       the LABEL is omitted, the loop control statement refers 
       to the innermost enclosing loop.  This may include 
       dynamically looking back your call-stack at run time to 
       find the LABEL.  Such desperate behavior triggers a 
       warning if you use the "use warnings" praga or the 
       -w flag.

The docs imply its the wrong behavior (any feature described as
"desperate" is probably dubious) but kept around for historical
reasons.  This feature should probably be deprecated and the warning
on sub foo { last } be made more severe.
