Yes, that is true. If the shackle is vertical, then when the spring is "unsprung" (as in: axle moves away from the frame) then the shackle moves inward and upward. When the axle tries to come back up again, the spring has nowhere to go and ends up wrinkled up real bad. Of course this only happens on extreme cases and I don't think that the PW springs will care much, but it might wipe out the pins in a hurry.
