Q92Skald's Training: Benefit: You swap your majestic word for the skald’s aura power. You and your allies can use minor actions to benefit from the aura only as many times during an encounter as you would be able to use majestic word.

If one were a Hybrid Bard with the Skald Training feat and thus had only one use of Skald's Aura per encounter, does this mean one need choose between the healing minor action of the Aura and any minor action AW power, like Song of Serendipity? Or does the restrictive text italicized above refer only the healing effect of the Aura?
