Yes.

No if buffer-file-name of the buffer doesn't match with
"\\.po[tx]?\\'\\|\\.po\\." (an entry in file-coding-system-alist).

First of all, po-mode is not included in Emacs.  Emacs
currently just provides a way to detect coding-system for PO
files.

If a buffer is given to find-operation-coding-system,
treating buffer-file-name of the buffer as a file name is
the natural thing.  And to make it work, we must set
buffer-file-name of the PO file buffer decoded from
test.po.gz to test.po just while callding
find-operation-coding-system.
