The man page says:
       The  order  of expansions is: brace expansion, tilde expansion, parame-
       ter, variable and arithmetic expansion and command  substitution  (done
       in a left-to-right fashion), word splitting, and pathname expansion.

So it follows that when $2 is expanded in your function call
(parameter expansion), it is too late for any resulting tildes to be
considered for tilde expansion.  Function parameters are not special
here; this applies to any parameter expansion.
