I think a response of 1♠ is mistaken on the North hand and he should bid 2♣ (and I am not just saying that because I have seen South's ♣ suit!)
If the bidding starts 1♥ 1♠ 2♥, North no longer has a sensible bid. He is too strong to sign off in 3NT or 4♥, so he is practically forced to bid 3♣ in order to force. Now if partner bids 3NT you are again stuck! Should you leave it or take out to 4♥? And I don't think bidding is any easier if partner gives preference to 3♠ or makes a probe with 3♦.
Also if opener might raise a major on 3 cards, you are in a tricky situation after 1♥ 1♠ 2♠. Unless you play quite sophisticated methods it is very hard to determine the correct contract (3NT, 4♠, even 6♣ if partner has a perfect 3514).
These problems disappear if you respond 2♣.
Firstly, if partner rebids 2♥, you can force at the 2 level with 2♠. Now partner's possible NT rebid is at the 2 level and you have room to explore if you want.
Secondly, opener will only raise 2♣ to 3♣ with a 4 card suit (and, playing SAYC, with extras). Now you have an easy route to look for a ♣ slam.
Thirdly, ♣ is a much better suit than ♠, and you shouldn't bid bad suits on good hands if you can help it. Here for instance, a singleton ♠ for opener is better than a singleton ♣, but how is he meant to diagnose that if you bid ♠ and not ♣?
