Usually they don’t understand the auction at all. 2NT* (not necessarily balanced and therefore alerted)-3♣* (puppet stayman)-3♦* (4-card(s) M)-4♦ (both M, not alerted but I will warn before the OL less experienced opps that it’s not what they might think) get their heads spinning and quite often irritates them. “We play normal bridge!” or something like that.
"Don't understand" may sometimes be unjust, but at least they find it difficult and resent the fact that it is not "normal". I agree, just don't see what it has to do with Alert, they usually ask for explanations and the outcome is the same in any case.
We play a variant of true puppet stayman over both 1NT and 2NT, so it often goes something like 1NT("15-17") - 2
♣*("asks for 5-card major, does not promise strength or a 4-card major") - 2
♦*("no 5-card major", "has he a 4-card major?", "you know as much as I do", frown) - 2
♥*("asks for 4-card spades") - 3
♣*("denies 4-card spades, shows max HCP") - 3NT - p.
They seem to find this more stressful than 1NT("15-17") - 2
♣*("Stayman") - 2
♥ - 2
♠ - 3NT - p, even though "Stayman" means nothing, 2
♠ may or may not have been forcing and the final contract is exactly the same.
I would have more sympathy if they resented not knowing whether opener has 4-card hearts
