I guess in the specific example he gave, if bn is the sequence on the right then the inequality is indeed strict, since |xn-yn|/(1+|xn-yn| < 1 always, hence every term in the sequence on the left will be strictly smaller than every term on the right. He should have been more precise.

Why us an+1 - an strictly greater than zero? Could the n+1 term in the x sequence and y sequence not be equal to each other and thus give us a modulus of zero?

I don't think you should use i in the metric defitinion because it confused me between index and imaginary number

Epsilon should be kept the same for the contradiction, and just reverse "there exist" in front of N by "for all", instead of "not exist", and at the end, reverse the inequality |an - supT| should be greater or equal than epsilon

You are so rigorous sometimes I just have to skip forward :-P But good videos non the less.
