Because GIB doesn't know it. I think it plays 4NT as natural in this auction.

Clearly a very useful way to play it, as after an opening bid and raise you often hold 28 HCPs or equivalent playing strength in your own hand...!
It's a pity that GIB operates on rules rather than meta-rules. A meta-rule "4NT is only natural if partner's preceding bid was a natural NT bid" or similar would cover all situations.
As to the OP: mouse-over a bid first to get an explanation. If there isn't one, assume the bid will be taken as natural
Besides, you don't really have enough for 4NT on this auction IMO. Opposite little from partner you're down at least 2 in 5mX while 4H may not even make.ahydra

Included in v29.
It captures 1-3M opening - 3-4M raises - 4NT
