421.5. If the loop contains optional actions controlled by different players and these actions don't depend on one another, the active player chooses a number. In APNAP order, the nonactive players can each either agree to that number or choose a higher number. Note that this rule applies even if the actions could exist in separate loops rather than in a single loop.	421.5. If the loop contains more than one set of optional, independent actions, each controlled by different players, then the active player (or, if the active player is not involved, the first involved player after the active player in turn order) chooses a number for his or her set of actions. Knowing that number, the remaining players, in turn order, each choose a number for his or her sets of actions. It can be higher, lower, or the same. Then each set of actions occurs the appropriate number of times.
