Thanks for this explanation.
So the concept here is that whenever you are in front of VSAs and furthermore you suspect that the Vaisala method had to be applied, _never_ try the game of looking at orbit similarities: when the orbit parameters are reasonably similar you will be necessarily led to think that the the objects are more similar than they actually are due to the mean anomaly being "artificially" set to a value close to zero or 180 degrees.
So now I understand that the same explanation is valid for two other TNOs: they are 2002 PV152 and 2002 PX152, also seen in August 2002 like the ones we have discussed, almost in the same days.
I also suspect that the same explanation holds true for two hungarians, 2011 HO2 and 2011 HP2 that were only seen on 2011 April 25th, 26th and that I considered (wrongly) to be strangely similar.
Maybe the only strange thing in all these TNOs and hungarian cases is the fact that couples of distinct objects were discovered almost in the same moment and in the same area of the sky, but this does not mean that they are the same objetcs or that they are like "twins".
More observations are needed.
Cheers,
Alessandro
