Guys,
Another factor here is the sampling frequency. Your own aircraft data can be collected at your front end at a high frequency, so the motion can appear smoother, but the enemy aircraft data is probably sampled at much lower frequency, partly because it can only be sampled as fast as it arrives over the net, including any change in net lag. Any kinks in the motion may also be influenced by the patented net code that HTC uses to smooth out delays in the data flow.
This can be apparent if you get a film of the same fight from two players and watch them both one after the other from each players perspective. You can sometimes see that things don't look quite the same from both perspectives, a difference caused by net lag. When you have been playing long enough, you learn to react early to compensate. For example, if you think your opponent is about to get a shot, from his perspective he is probably already pulling the trigger, and you are probably going to hear the pings just as you pull that fancy jink that you just executed a fraction of a second too late. If the film viewer simply updates the film file as the data for enemy aircraft arrives, the film will be influenced by those delays. So if you are looking at a round trip delay between two players of 300ms, and your opponent is flying at 150mph his position will change by over 60ft during that time. For the same two players with a round trip delay of only 100ms the position change at the same speed will be just over 20ft. So fluctuation in net delay between those two values could cause a change in position of over 40ft. Also, changes in stick position will be lost during that time, making stick movements look as though they jump around when the position is updated. It will also depend on if the data sampling rate for the enemy aircraft is fixed at a constant rate in the film viewer or if it is dependant on the data flow rate. Either way, if the Film viewer is recording data at a lower rate for enemy aircraft, that may be the cause of the kind of motion you are observing.
