Phil posting it in a way to show "Well, I tried..."
He had said in a seminar that "the dude just doesn't like me".
By showing that he is trying to follow Kai, and Kai blocking him, it makes Kai out to be the instigator.
Phil, is taking Shawn Ray's "head game" tactics to another level. Remember The O will be here before you know it. Mentally messing with Kai can mess up Kai's training---he will lose focus and have some type of concentration on Phil.
I could be wrong, and Phil was just messing with Kai, with no alterior motive.
