Nothing wrong with that. When you can graft subtrees from one part of the tree onto another part of the tree, it can influence the score in odd ways. IE Fine position 70 really takes 26 plies to see. But almost everyone solves it way before ply 26. I typically get it at ply=18 for example, but only because of hashing...
