Good point. :)

Why?! -- because I didn't see the intended solution of going back to the faith plate - I only shared it because, I 1) had not seen it used before, and 2) thought it was kind of cool that the physics work that when the bridge is taken away the cube not only falls but is pushed slightly outward by the the solid floor (as part of inducing a torque). And, in my mind, this is not a "cheat" but an alternate - it uses not fancy moves, timing, or anything else - anyone could do this.

So you're hacking together a more consistent way to fling the cube just to avoid shooting it on the faith plate? Why? The faith plate is so elegant and Demon Arisen can simply move the wall adjacent to the exit room further back to block this. Creative, though!
