yes
you are incorrect
the low limit screw only affects how far the derailleur moves inward
and the high limit screw only affects how far it can move outward
a limit screw only has effect on the derailleur
when it is at the limit
and has no effect between limits
edit
if you post a couple of pictures of the derailleur
and how the cable is routed and clamped
it might give someone a better idea
