That example is impossible. Pretend you are opener with that hand, you know your partner is 4-5 in the majors with 3 controls but you don't know where they are so you could be off an AK.
If an open AK was physically impossible, then opener would have to have to have an A or K in every suit (try it). So opener would have to have something like:
Kx
Ax
Kx
AJT9xxx
And his partner would have to have something like:
QJxx
QJxxx
Ax
Kx
if you think that that's sufficient to force game (with no fit, that seems pretty optimistic to me). He can claim for 12 and gets a 13th on a heart lead and possibly on a small spade lead.
I think it's more likely that he's willing to risk having an AK open and you not finding it opening lead, believing that if you don't find the killer lead that he has 12 tricks off the top (the AK and 10 tricks in the minors).
As for whether the contract is unusual, well, you and your partner would find 6NT with the two sample hands, right? Using a saner auction, of course.
