West' 1 NT should show a) 15-18 b) balanced c)a spade stopper. One of 3 doesn't describe the hand well to pard.
Difficult for South to bid on. At another table without interference they raised 2S to 4S. Possibly an invite is better. Think of that perfect minimum - pard could have ADQD. In these situations expert partnerships will make a game try in another suit, either a long suit or suit short game try, so pard can identify whether his limited HCP are "working" or not.
For South the 1 NT overcall suggests game is unlikely and his KD is downvalued as the AD is likely to be sitting over it - so uses the oppo bidding to avoid a bad game.
