crab, you are correct, roll to the right is from the high TR position. now think UH1's it is even worse than a robbie.... but we have a little more weight to start with.
this is another reason for slight aft cyclic BEFORE you start bouncing through those hills. as you slow down, you end up with less nose down, therefore the TR also comes down, compared to MR level, and can produce less of a turning moment on the fuselage when you start to get bounced, if the bounce even produces a loss of G, or because you already have the disk well loaded you may just get a bounce.
worst combination is 1 up, low on gas, returning to base at VNE, in the lee of some big hills on a windy day, and how many of us have done that? luckily the ol JR doesn't really want to get to VNE straight and Level...
