I don't see how this could be right.

If the blade is flat when it starts up, even if the differential
speed were to make it "want t cup", wouldn't the firces on each side
equalize?

By the same token, if you were
to mount a rod perpendicular to a rotating shaft, the rod would want to
bend because the tip would be travelling faster than the part
nearer the sghaft. What direction would it want to bend in?
