Tilde expansion is tricky stuff. If you read how it is defined (man
ksh), it says:
====
The characters following the tilde, up to the first `/', if any, are
assumed to be a login name.
...
If the login name is not found in the password file or if any quoting
or parameter substitution occurs in the login name, no substitution is
performed.

I think that explains your testcases.
