The chances of South having a trump stack penalty double on this auction are too remote to make this a penalty double.
I'm sorry, but this isn't quite true.
This is a penalty double by default: when you pass over an overcall and later double the same suit, that is a penalty double by definition. Now, of course you can agree to define the double as something else if you wish. However I believe it is also correct that it is a penalty double by agreement.There are two reasons to play this as a penalty double, and you need both of them to be valid:
i) It is quite possible for you to have a penalty double. Look at other hands on this forum: 5-card overcalls at the 2-level are very common. A delayed raise may be only a doubleton (particularly if West thinks double of 2S is penalty). There is no reason the 2S reopening cannot have a heart void. South could have six of the things, never mind only five of them...and there is certainly no reason that the opponents can't be in a 9-card fit missing KQJ10 of trumps.
It is negotiable quite how 'penalties' this penalty double should be: whether it is a real trump stack, or a singleton/void spade and some honours in hearts. But either way it is not expecting opener to pull on a down-the-middle hand for the actions to date.
ii) I can see little need to use such a late double to mean anything else. Opener has shown a spade single-suiter unwilling to defend 2Hx opposite a penalty double. Responder has denied the values to act over a 2H overcall. With a doubleton spade he would raise spades. Why would he want to get involved in this auction with a singleton spade?
