The link is having one PNR referring to the other. When the system does its sweep, it cannot detect the reference. Therefore, it causes the non-elite losing E+ seating. When that happens, just call UA and have the non-elite put back into E+, next to the elite.
Checking your itineraries shall be a daily exercise detecting any seat change.
