Side View Combat With Movement Actions When Attacking.

So I found this wonderful script: http://cobbtocs.co.uk/wp/?p=57

Found a modified one that I am using: http://pastebin.com/X6JKUMm5

I don't know how to script yet but I been trying to learn. I was wondering if anyone could help me modify the Pastebin one so you know where the character seems to blink when they do their action. Maybe they move slightly ahead and then back after their attack is done. Sort of giving it a better and clear understanding who is performing the attack.

Here is a demo video of the fight:
