WTF is this?

I love to watching the Championships of Titan Server, and i found this resent Vid of Titan. There is my favorite player in all US Atlantica, Sharingan.
I like how he fight, i like that he allways try to use some low class mercs in his formations, and i love his strategy, but.... this weekend he did something that i don't understand.

All i want to know is WHY? Why in the name of God did he do that? Why?

If you know, any of you know why, please let me know. This was sad, sick and stupid!
