QR also doesn't satisfy [[Later-no-help]]. In particular, in a three candidate scenario where A has the most first preferences and C the fewest, C may have incentive to insincerely create a majority win for B over A, if the C voters believe C has the second-preferences of the A voters. So, while the A voters technically have both Later-no-harm and Later-no-help guarantees with respect to A, there may be an incentive to withhold their second preference if they feel other factions are relying on those second preferences in order to try to steal the race from A.
Note that the supporters of the top two candidates (by first preferences) have both [[Later-no-harm]] and [[Later-no-help]] assurances. Labeling the candidates A, B, and C, the A voters' lower preference is only counted once A is known to have lost. The B voters' lower preference is not regarded at all, because candidates are only compared to their "adjacent" candidates in first-preference order, and A vs. C (the race that B voters can influence) are not adjacent.
