I don't know why they do it. But it seems to happen frequently, even last year.
While not odd, but still of note, is that venus29 and venus30 and the 747 82-8000 all took off in what seemed like minutes of eachother and flew to nearby airports to perform the same manuver. venus40 and venus67 took off shortly thereafter.
Remember if they have their adsb radio on then they want to be seen, they can always turn it off.
