Phoenix doesn't alert to name changes, since it's a feature of Plus! itself. Phoenix alerts to status changes.
To enable Plus!'s name change alert, go into the Preferences panel, Notifications page. It's the second tab on that IIRC, and the option is 'Alert when users change display name' or similar (on a uni Linux box, so can't check).

BTW, the screenie could be updated to the 2.01 version.
* RaceProUK makes a note to put screenies on his own site.
