Yes, it leaks memory, yes, you could write a DESTROY like that, and internally Perl uses reference counting so that your destructor should not be called until all references are gone. (The current implementation will call it when the last reference goes. This deterministic behaviour may or may not survive. People like it and use it a lot, but there is constant grumbling about implementing real garbage collection some day.)
