the one in the above pic seems to pivot outwards, the pivot point is placed next to the outfeed table, by pushing against it with a piece of wood, the guard moves to the left away from the fence.
looks like a mirrored version of the porkchop type, wich i believe rotates toward the front.

this may actually be safer, but you don’t want it knocking your fence out of square when it closes back, some kind of stop would be neccesary to prevent it from hitting the fence!
