the first technique is great and should be everyones go-to when dealing with the DLR but the second move where he steps back is just asking to be single leg'ed.
some added details to help if the guy has a really strong DLR would be to shove the hook off with you hand and while your hand is down there, pop the grip up off your ankle, then side stepping your leg over to a knee slide position immediately to prevent your opponent from reestablishing the DLR.
