Maybe this is aimed at votes where several different motions are considered by the one vote : propasal a = 21 votes, proposal b = 19 votes, proposal c = 22 votes for instance. Now if proposals a+b concerned motions to fly down the east of the country say and proposal c was for down the west side say I could see the point.
We all know what happened when the snfc rule came it too play a few years ago when the overwhelming MAJORITY vote was deemed to have failed because of their stupid outdated constitution, the minority prevailed.
