[amsat-bb] Falcon 9 video - moving early?

[vk1pe.peter]

I think that my eyes are not deceiving me.

See http://www.youtube.com/watch?v=sP5gykvTBpM or http://bit.ly/dx9Vot. 
Falcon 9 appears to move at about T -3s. The count is still running 
towards zero in the video, and the "call" seems to be between 4 and 3. 
What do others think?

Also, were the umbilicals meant to "tear away" (as it moved) or "drop 
away" (before it moved)?
