a. Essentially, if a set of players have played and won the same number of matches,
and 2 are tied, it is decided by H2H.
b. In the same scenario as a. but if 3 are tied, then it is decided by sets won. If one player has a better % than the other two, then he is ahead. If that leaves 2 still eligible, then their placing is determined by H2H. Anytime you have only 2 tied, it reverts to H2H.
c. In the same scenario as b. (3 tied), if all players have the same % of sets won, then it goes to game % won. They are ordered according to that, and then the same rules apply as described in b.
d. If 3 players all have the same set and game % won, then it goes to according to ATP ranking on Monday following Paris.
So in the scenario you describe, c. above will apply. Roger will win the group outright with 3-0 record. The other 3 will be 1 and 2 with equal sets (b). The player of the 3 with best game won % will be second in the group and the others will be eliminated. If two players have the same game won %, then the 3rd is eliminated and the player with that won the H2H will be second in the group. If they all 3 have the same game % then d will apply. The player with the best ranking will be second in the group and advance with Roger, in this case, Nishikori.
