Ability to skip lever puzzle (exploit?)

[amnPlayer]

So I found a way in Amnesia for you to to be able to skip the lever puzzle that is located in an adjacent room from the big room that has two dynamic bridges that you need to operate.

Instead of actually doing the puzzle to get the second bridge to descend, you can use a brick that's coming out of the wall next to the stairway leading to the platform you need to go to jump there.

I've done it successfully only once, and on second play I wasn't successful.

Is this a known issue?

By the big room I mean the open-air room that has two bridges, and a passage to a corridor filled with water, and the puzzle of oiling a switch to lower a set of stairs a few times to break a pipe.
