you are not required, nor should you be exactly over the top
Capt Mo is dead right on that one!
Seriously bad airmanship by the guy in the twin
You're assuming the guy in the twin didn't understand the situation better than you. Most of them being IFR & dual COM chances are he would have had updates on your position on RADAR & be listening on BK TWR.
I myself have on occasion done that exact thing to ASSIST the flow of traffic & being certain to report the aircraft in front "is in sight"
Last thing anyone needs is a twin orbiting over 2RN in order to stay behind another aircraft.
BK TWR is able to see local traffic on radar - there needs to be some thought given to whether they can give advisories
There is such a system known as SY RADAR, should listen to it, its tops!
None of what I have said is directly related to this accident, its a tragedy & something that will unfortunately continue to occur from time to time
