Unless I've missed a very recent press release then coaching is allowed from the snake side, just not from between the fence and the netting.
Snake side will be presumed to be the one furthest from the pits/closest to the spectators, whichever way you want to phrase it.
Edit: Also, your first quote says that 'spectator side' coaching is removed, well, regardless of what the field looks like, there is only spectating from one of the two sides, so that hasn't changed, therefore this thread is a waste of time as you have the answer in the first place. Idiot.
