Push Install SEP 12 and UAC needing to be turned off

I hope I read this wrong

Condensing this TID to the essence it says:

1. If a push install fails for a computer see if UAC is on.

2. Turn UAC off.

Lets imagine this in a large enterprise:  500 pc's or more and wanting to upgrade to prevent a vulnerability.  UAC should ALWAYS BE ON.

So my reading of this is that through one fashion or another I have to turn off UAC for the 500 computers to allow my push install to work.

That seems to totally destroy the concept of a push installation.  If I have to touch via remote or otherwise 500 computers, what efficiencies do I lose since I can't install via PUSH if UAC is on.

  If I have to turn off UAC what labor savings have I lost and how much more time will I burn on what used to be a fairly painless installation.

Please tell me I read the above article wrong.
