You're supposed to use the beam to lower the rope into the upper chute (which sets ROPE-PLACED to true), but it also allows you to do it with the lower chute (which sets ROPE-IN-LOWER-CHUTE).
So if you look at ROPE-F, you'll see that it checks both these variables. For whatever reason, BEAM-F only handles ROPE-PLACED.
I'm not sure if this causes any actual bugs, but it does seem inconsistent.
