It does not.
You get a +4 dodge bonus to Armor Class against attacks of opportunity caused when you move out of or within a threatened area.
There are differences between 'movement' (for game purposes) and a move action. Specifically, however, you aren't moving within or out of a threatened area for purposes of Mobility. (In this case, moving 'within a threatened area' refers to movement that keeps you in their threatened area, not just actions which might involve moving, like jumping in place, waving your arms, or digging in your backpack.)
