Pai Gow Poker Houseway question

I see a curiosity in the Golden Nugget's houseway.

Quote:

Four of a kind: Play according to the rank of the four of a kind:

2 through 6: Always keep together.
7 through 10: Split unless an ace or better can be played in front.
Jack through king: Split unless hand also contains a pair of 10's or higher.
Aces: Split unless a pair of 7's or higher can be played in front.

With higher quads, the premium of a superior pair up top becomes greater, so the conditions for keeping those quads together become stricter. 2-6 are always kept together. 7-10 are kept together if you can put an ace or better up. For J-K, you need to be able to put a pair of 10s or better up...but for Aces, the restriction is lessened. Only 7s up are good enough.

Why is this? It seems counter-intuitive to me. It almost seems like the house would want to always split quad Aces.

Good pick up. No way I split 4 jacks with a pair of 9's. JJJJx/99 seems far better than JJ99x/JJ

It is.
The EV is +.87 versus ~ +.73
