The leeward boat cannot "force" another boat to tack. If I'm the weather boat, I'm not going above head to wind. If I keep clear until you are head to wind, I've satisfied the requirements of rule 11. If there is contact after that, then you've gone past head to wind (and thus subject to 13) - and you're out.
