Yoko gake was my initial thought... Actually nidan kokosoto gari was initially what I thought he attempted, then I changed to yoko gake and finally settled on some kid of yoko otoshi. I would concede yoko gake I guess, though I was always taught that uke's leg should be knocked from under him, rather than being blocked and pulled over it.

I thought tori clearly attacked with sutemi waza, but I imagine that debate could go on for a long time so I'll just agree to disagree, though I mean no disrespect by doing so.
