Do you have to spend one use of Dimension Door if you make multiple teleports during the Full-Attack Action?

EDIT: Replace one use with additional uses.

Dimensional Dervish

You teleport with a mere thought, savaging your opponents as you flash in and out of reality.

Prerequisites: Ability to use the abundant step class feature or cast dimension door, Dimensional Agility, Dimensional Assault, base attack bonus +6.

Benefit: You can take a full-attack action, activating abundant step or casting dimension door as a swift action. If your do, you can teleport up to twice your speed (up to the maximum distance allowed by the spell or ability), dividing this teleportation into increments you use before your first attack, between each attack, and after your last attack. You must teleport at least 5 feet each time you teleport.

Special: A monk can use additional points from his ki pool to increase his speed before determining the total speed for this teleportation.

It would seem that only one spell is used and the teleportation from that spell is "divided into increments", not multiple spells. As least that is how I read it.

cnetarian is correct. Dimensional Dervish is a really fun feat but it does limit the range of Dimension Door. Normally DD is like 400 feet + something per level; with this, casting the spell limits your distance teleported to twice your speed, but in return you get to blink around like Nightcrawler.
