IAC, it seems clear that the WBF minute allows players to examine their system cards after the final play and before the end of the play period, whatever Law 20G2 says. Note also that 20G2 refers to 40B2b. Technically these laws may be in conflict, because the former refers to "during the auction and play periods" and the latter only prohibits looking until "the end of play". I suspect the minute was intended to clarify the intent of the law - which is extremely unlikely, IMO, to be to prohibit players looking at their cards except between rounds.
