Why retaliation and bladestorm together?

In watching Swifty's old wotlk videos:

I notice he usually uses retaliation and bladestorm together. What's the logic behind doing that?

It seems to me that retaliation is useful in encouraging opponents to get away from you and not dps you. But bladestorm accomplishes that alone, doesn't it? Opponents usually try to get away from you when you pop bladestorm so it seems redundant to use retaliation as well. I'm sure there's a good reason for it; just wondering what it is.

Also, on another note- do ret paladin judgements and divine storm (10 yard and 8 yard range) cause them to suffer retaliation damage?

Swifty bestest warrior, you never question his judgement

The only reason you may use those abilities togheter is to free yourself from a root effect or a slowing one while you have used retaliation earlier? I don't know. By the way, you can use retaliation also to counter attack any king of melee burst. Your enemy will stop attacking you, giving you the time to attack him (if he can't kite you) or he will die by his own damage so it's kinda winner move. Bladestorm can be used for many purposes: bursting damage (it can be stopped only by disarm or it can be kited), getting out a root or snare effect, countering a crowd control like cyclone, sheep or hex, forcing your enemy to use a defensive cooldown... etc etc. If you realy wanna watch good warrior pvp movies check out Hoodrych and Zage.
