The @(./) part is wrong.  Globbing doesn't handle directory path
components in that way.

unicorn:~$ echo *.pdf
1040A.pdf 34282.pdf [...]

unicorn:~$ echo @(./)*.pdf
@(./)*.pdf

You're basically asking bash to generate filename matches which include
the substring "./" within the current directory.  No filename can contain
that substring, because it has a slash in it.

Also, there is absolutely no benefit to putting the "*." part inside of
an extglob expression.  It works, but it's extra syntax for no reason.

What you want is simply this:

./*.@(xz|other)
