Forum:Hyperion Gift Shop trap door used twice

I was going through the Hyperion Gift Shop again, and on the way out noticed that I had "X Use" at the switch you hit to open the door in the floor. I used the switch and heard a door open. The use option then disappeared. Is this like in DLC 3 when you hit the switch by the red chest to open the door into the Meat Popsicle's room (with the modified Lilith poster), or is there nothing to find with this?
