If this wasn't the matchpoint of the set at 29 all, I wouldn't overanalyse just one rally. You lost one point. If you loose quite often this way the point, you need to think about your game. But this small sequence is not enough to see enough from you, to say what mistakes, you do on regular base. One mistake is a mistake, a bad shot selection is a bad shot selection, but it gets a serious problem, when you do something on regular base wrong.
Also the comparison with pros, with all respect, is something which I don't like, because even if you play a decent level, the game play is noticeable different and the abilities of you and your opponents are lower compared to pros. So be focused on yourself and don't think too much to play like LCW, because with all respect, you are not LD or LCW and your opponents, too.
Edit: After I slowed it down to 0.25 I noticed that you realized lately the shot to the backhand and anticipated a flat lift in the forehand, so this is the reason, why you needed to play the backhand. You can see clearly that you tried to move to the forehand corner first. I would kee p an eye on my recovery and start. My impression is that you are fast enough and could avoid it. I had played a clear or a drop, too like robert mentioned.
