Actually yes, because it's not the case for the right side of assigment.

Looks like you ran out of arguments here

I ran two simple FOR loops with 1,000,000 itterations incrementing variable lnCounter inside. One with m.lnCounter on the left side of assugment, another with lnCounter
m.lnCounter = 0
m.Start = SECONDS()
FOR i=1 TO 1000000
    m.lnCounter = m.lnCounter + 1
ENDFOR
? SECONDS() - m.Start

m.lnCounter = 0
m.Start = SECONDS()
FOR i=1 TO 1000000
    lnCounter = m.lnCounter + 1
ENDFOR
? SECONDS() - m.Start

At least we can agree on that :)
