Obviously its fine to respond 2C, if that is your agreement. Its also fine to respond 1S, if that is your agreement. I lot of people round my way play that 2N over 2S would be a forcing inquiry. That would work perfectly fine here, north would bid 3c naturalish promising 4 clubs and only 3 spades. next hand bids 3H and you are all on your way to slam. (Obvio this is now GF as you could have 3H over 2S as NF invitational in this set up).
In so far as there is an error, it is that north undervalued his hand by bidding 2S. 2C then 3S over 4sf works great on this hand, you have shown your whole shape and your strength is limited. Admittedly you would need some artificial continuations to be sure about strain, but here that doesn't matter too much, south is only missing 14HCP is non diamond covers, so is very excited.
Actually, I just discussed this type of sequence with a friend of mine, who mentioned that R-M apparently play that 2S is a GF artificial call in the sequence 1
♥-1
♠-2minor-2
♠ (opponents passing throughout). Hence, Responder's repeat of spades is artificial and says nothing about spades -- that is the forcing call in that sequence. With long spades and a weak hand, you do something else "intelligent" here.
That said, I do not know whether R-M would bid 1
♠ with a three-piece heart suit and GF values (and would be rather surprised if they do). I also stand tentatively by my statement that 1
♠ caused the problem, in that although this specific auction might be unwound even with that call, I believe that approach to be problematic in many other sequences. I may well be wrong, as my concerns may well have been alleviated by those who use that method of bidding (like with the apparent R-M 2
♠ rebid).
As a general note, though, it is not necessarily correct that any call in any given sequence is "fine" simply because that is the agreement. If that is in fact the agreement, then the call might be forced upon the person making that call, but the agreement might be unworkable, unsound, or otherwise not ideal. It might be workable, sound, and ideal, as well. Or, it could be workable, sound, and relatively neutral when compared to other methods.
