now I have two typeglobs pointing to same address

No, you have two references pointing to the same (ie a single) typeglob. undef $a causes one of the references to the typeglob to be freed (the typeglob itsself is not yet freed, since $b still contains a reference to it).

If in addition you do undef $b, then the typeglob will be freed. But it's not clear to me what you are actually trying to achieve.
