is there any sense in this?
I don't think there is, no. I think it's a psychological artifact. More accurately, if one of the players does not know how to accurately range villain, then yes, shoving first could be preferable simply because it will exploit villain's leaks. But if both villains are rational and can accurately range their opponent, then I'm pretty sure that being in position is strictly better, and that the fact that the OOP player can shove first does not help him (because the IP player can call appropriately wide).
