Deadlift Form Check at 350

[Giri Kotte]

Just watched his second video. His knees look fully extended to me.

I refer to the first, third and fifth reps in the first video. But even otherwise, how important is it to lock out completely beyond the point the load vector at the knee joint is perpendicular to the ground?

I watched his first video. He locks out all his reps there, too. If you don't come to full extension, you have not finished the rep, however.
