Why try and confuse/complicate a straightforward rule? 7-1-7-c is clear, once an interior lineman puts a hand "on or near the ground", he has locked himself into that position. However he decides to move (slid, slip, wiggle, drag, lift, remove, convey, displace, abolish, separate, etc.) his hand from that position it's a "false start", IF the covering official sees the movement & understands 7-1-7c well enough to recognize the violation & kill the play.
