Permanent spells via Spell Timing mystery

It seems that the ability for initiates of the spell timing mystery (pages 100-101) can have relatively easy access (+6 magnitudes) to effectively permanent spells, in pretty much the same way as you can create items with constant effects: have a recurring spell which lasts long enough to cover the span between two recurrences. The last paragraph seems to confirm that intent.

Is that also how you read it? Do recurring spell effectively last forever?
