The failure to play the three games which were agreed drawn means that these games should not be counted for FIDE ratings purposes.This very correct decision closes some parts of the whole St George Club Championship fiasco. Mr Bekker's announcement supports the view that agreements to draw can only be made "during the game". See law 5.2.c in the Laws of Chess.
Clearly, if players become unavailable, for whatever reason, later in a tournament - then they simply should not be permitted to agree to draws for their remaining games. They are either withdrawn or forfeited.
