Yes! You are correct. I have a split leaf, and when I bought it about two months ago it was under duress. Now it seems happy.
The most mature leaf (top), has always had only one split, and the rest had none. It has not changed since I bought it except for growing larger in width. But the new leaf unrolling has 3! This plant was not marked when I bought it, so I do not know if I have a standard split leaf or a monstera yet.
