Why? West's actions look obvious to me.

Lets look at it according to both agreements,
First, 1
♠ denies spades. Wests hesitation reveals that something has gone wrong. And was Checkback available? If so West might well have thought that rebidding spades would send a clearer message that he really did have spades. Of course the hand may have been considered too weak for Checkback. Anyway the hesitation and the 2
♠ bid sends thnecessary message, especially as many players would bid 2
♦, describing the hand better and eliciting secondary spade support if partner has it.
And of course Easts fielding is red. Why is 2
♠ after denying spades not a notrump probe?
Suppose though that 1
♠ shows spades. Wests hesitation sends a similar message, ie that partners explanation was incorrect. Still a reason not to try Checkback or 2, and I ask again, why is 2
♠ after denying spades anything but a notrump probe? I understand that it could have some other meaning, either artificial or suggesting a Moysian if partner has 4 spades. Or something else. Not 6 spades.
Making a seemingly straightforward rebid following a break in tempo is very suspect, and here the message is extremely clear playing either agreement.
