4♠ sounds like a suggested final contract, so hopefully North's strength isn't really unlimited (it says 13+); I presume he would do something else with, say, 19+ opposite partner's opening bid. What would bidding 3♠ instead of 4♠ show, since we are in a "forcing the 3NT" auction?

i think GIB plays fast arrival, so 4♠ is not as good as 3♠. Whether this is reflected in the explanations I don't know.
