Some additional info:
We (SBN) made those documents to hand out to new players. We did not want to make the read too extensive, so not all "unlikely" or "extremely rare" cases are pointed out. It could easily become a 10-pager which no new player is interested in.
At the start of a tournament, if there are new players, the referee or someone else often summons all new players for a quick and short demo of the rules, especially regarding the movement rules.
So, ultimately, while not complete; it is not the goal to give a complete and exhaustive book of examples. The fundamentals are explained and based on this, we feel all situations can be derived. For example: Counter chasing can be derived with the fundamental info and guidance from a referee.
Is it a perfect document? surely not, but we feel and hope it serves as solid starting point. If we were to explain all hypothetical situations one could come up with, the text would become as long and unpleasant as the GSFR on here.
