The exact same argument applies to West - if West had 4 spades they chose to play the 6 from K964, instead of the 4.
But as manudude correctly, imo, pointed out, most players do not randomize low spot cards as often as they should. Indeed, if one plays suit preference in trump, as a lot of good players do, one gets out of the habit of randomizing even when, as here, suit preference isn’t likely to provide useful information. So the spot rates to be honest.
