So there used to be (a couple of months ago) a prohibition of 2-oceans in the *A award rules but not in the MP rules. We all know that for all intents and purposes it didn't matter because the website always booked flights as MP awards and agents generally did too.

I checked today to answer a question in another thread and the rule has been removed from the *A rules page too.

Also I can't remember if this prohibition "Circle trips are not permitted. For example, you cannot fly from San Francisco to Hong Kong, to Auckland and back to San Francisco." was always in there or is a recent addition. Again it appears in the *A rules on UA.com but not in the MP rules on the same site.
