That's not substitution-jutsu. That's Shadow (or water or sand or whatever) cloning.

With sub-jutsu just when you think yo0u've got a powerhouse ninja in position for a killer move like Rock Lee trying to screw Gaara's head into the arena floor with a Primary Lotus it turns out he's slipped free (undetectably) and left an inanimate duplicate in his place.

The Hidden Leaf version leaves the enemy grasping an enormous chunk of firewood but other substances are seen from other villages.

On a meta level most uSes do look like expending an Extra Life but Sakura used it 2 or 3 times in a row in the forest of death section of the Chunin exam.
