Doing so allows you to switch to the new mode five seconds quicker. If you change from Astral Fire to Umbral Ice for instance just by using Blizzard, it takes 2.5 seconds for one Blizzard that just removes the Astral Fire and then another 2.5 seconds for a second Blizzard before you actually get the Umbral Ice effect. You could have had that Umbral Ice effect immediately and therefore an extra five seconds of its MP regeneration if you'd used Transpose. Similarly, once your MP is restored, you'll want to get into the higher DPS of Astral Fire quickly.

I've also gotten into a pattern of using Transpose whenever I end a fight in Astral Fire mode. That switch to Umbral Ice when the fight ends makes recouping MP to be ready for another fight significantly faster.
