Sent email only changes made thru other user

I wish change a default workflow to send a new email with opportunity detail is changed only for another user.

Today even owner change any detail system send a email, I think in this case not necessary

I tried include a new test if modified by last user = assigned to for do that, but not working.

See image

Doubt : this test verify any user or only if admin changed ?
