One-handed backhand in tennis

I am a one hand backhand player who was forced to use two hand grip for lessons back in the old days. I find that the technique is practically the same, the only difference is whether or not you use your non-dominant hand. The position of your dominant hand should be the the same in both one hand and two hand backhand. You should still turn, hit follow through in the same manner.

Of course if you do not know two handed backhand, everything I just said makes no sense, so in that case please let me know so I can explain it better.
