No no, this is a different room. It's true that the skeleton ape won't appear near the first bridge until you hit this, but one spawns in the room with you right after you hit the switch, and demonstrates blowing up one bridge so you'll know the other one can be destroyed too. It's a lot like this room in Super Metroid that shows you that the glass pipe can be destroyed, with the exception that it's already broken and doesn't require help from an enemy.
