It definitely matters if he had the WK MD springs since they're weaker than the XK MD springs.
Remember:
WK MD = XK LD
WK HD = XK MD
So when he said MD springs, if he meant XK MD springs then that's what I have and ill consider cutting a coil off. However if he meant WK MD springs, then those are weaker than what I have and ill therefore want to sell my springs and go with a different method of additional lift.
