Dawnflower Dervish Question

[ATHATH]

The Dawnflower Dervish (http://archivesofnethys.com/ArchetypeDisplay.aspx?FixedName=Bard%20Dawnflower% 20Dervish) archetype for Bards has the following ability:

Meditative Whirl (Ex): At 8th level, when using battle dance, the Dawnflower dervish can enter a trancelike state where his spinning motion represents the movement of the planets around the sun, and his spirit is attuned to the healing aspects of Sarenrae. By spending a move action focusing on his whirling, the dervish can apply the Quicken Spell feat to any cure spell he is about to cast (effectively spending a move action and swift action to cast the spell). This does not alter the level of the spell or the casting time. The dervish can use this ability once per day at 8th level and one additional time per day for every two dervish levels he has beyond 8th. This ability replaces the dirge of doom bardic performance.

So does this ability actually decrease the casting time of your Cure spells to a swift action (a few times per day), or does it do nothing but waste a move action and remove your access to Dirge of Doom?

Well the obvious answer is:
The text is immediately and clearly contradictory, so one part of it has to be an error and should be removed. Remove the one that makes sense.

Basically, it moves the casting of a Cure spell from Standard to Move action. As this is an old archetype, I guess this was supposed to either work with Vital Strike or allow you double casting for a round.

The intent is to let you cast healing spells while still having a standard action available, and without being forced to quicken a weaker/lower-level cure. Interpret it in whatever way helps you achieve that result.
