Cover, not the Paladin Job Ability.

Sometimes, although rare, there will be on the log that states the following:

Cover! Player starts doing whatever move to whatever.

What does that mean? I know it happens right when something happens at the exact same time a something is finishing, but does that do something than bring that to everyone's attention?

Meaning, if I start casting Stun on a mob right when my WHM finishes curing the tank, does that make the stun stronger, or just point out a continuance?

Its a text glitch, Means nothing really. Just like "Resist! blah blah cure V blah blah" etc.
