Do you have to permanently sacrifice turns/rebukes for more daily Devotion Feat uses?

Question

I've been reading Complete Champion and I came across a conflict the in text that I need resolved.

On page 52, in the Domain Feats section, the text reads:

If you have the ability to turn or rebuke undead, you can gain additional daily uses of a domain feat’s benefit by permanently sacrificing daily uses of that ability.

But under the specific feat it uses the word "expend", like you're just using a use/day of Turn Undead.

For example Travel Devotion uses the text:

Special: If you have the ability to turn or rebuke undead you gain one additional daily use of this feat for each two daily turn or rebuke uses you expend.

Answer 1

No, it’s a daily thing. Each day, you may expend a use of Turn Undead (as if you’d actually used it) to power a [Divine] or [Domain] feat, gaining the benefit of the feat instead of performing a Turn Undead action. When your spells refresh, so do your uses of Turn Undead.

Which is part of what makes Cleric such a great dip: anyone with a Charisma of at least 12 gets three minutes worth of Swift-action movement per day. On top of some minor spells, decent stats, and the opportunity to get another couple of feats from other Domains/Devotions (Cloistered Cleric can grab Knowledge Devotion).
