He's just saving face. I find it ironic that Lucky, Points Guy, Gleff and others dropped UA like a hot potato and have been gushing over all things AA the past couple of years and then seem surprised at these changes and how they were handled. Blissfully ignorant of the all the loopholes, tricks, and workarounds they taught their readers, let alone that AA/US execs read them too.
Perhaps all this hoopla will delay the other shoe(s) to drop, but its pretty obvious there is more devaluAAtion coming to US AAir.
