I've never heard that before.
This has been my understanding and my experience, provided the upgraded had already been confirmed.
I believe UA will preserve the upgraded ticket within their
JOINT VENTURE / ATI partners (all of which happen to be *A). However, rumor is that some are nastier than others at accepting an upgraded ticket (I'm looking at you, LH ಠ_ಠ ) even though the policy is to accept the upgraded ticket.
So said another way, the policy - as I understand it - is that one's upgrade
will be should be preserved on:
The A++ JV with:
AirCanada (AC)
Lufthansa Group (LH/LX/SN/OS)*
As well as ANA (NH) who UA works with under a JV for the Pacific
*assuming LH decides to follow the rules and accept the ticket.

Now, that's not to say UA would not re-acomodate a passenger in the same (upgraded) cabin on other carriers, it's just that it's not the default policy.
