So either that circle is a fabrication, an ET UFO or an unidentified [military] aircraft.
Or simply a very misleading interpretation. See following (Remember in the same presentation they also spun a story on the location of the buk on a truck video – The Russians claimed it was filmed in Krasnoarmeisk when it was in fact Lugansk)

In the above image one can see the MH17 Flight Plan track (a square) with a circle immediately next to it.
This occurs at 11:10 in the youtube clip.
What the RU MOD is saying is that the square is MH17 and the Circle is a NEW aircraft.
This is quite simply incorrect. The square is the theoretical position of MH17 now that its SSR has ceased to function and squawk its assigned code due to catastrophic failure.
It has uncoupled from the radar track and all that is left is a primary radar paint of MH17’s wreckage.
The RU MOD would like the layman to believe that the appearance of that little circle where MH17 was is the sudden appearance of a military jet (who would not squawk a code for SSR for reasons of concealment logically). The reality is that their automated ATM system is just like that of most modern countries and the circle is merely the remains of MH17’s Primary radar paint as it falls out of the sky, while the square is the expected position of MH17 based on what the ATC know of it.
There a couple of reasons why that paint exists on the ASD for an extended period of time
The first is that radar paints usually have a ‘coast’ time included in them. This means that when the data is incomplete or has just recently dissapeared, the radar paint will ‘coast’ on the ASD to allow the controller to see the last known location of the paint for a bit longer.
Furthermore, many ATM systems allow the controller to optionally select the ‘last’ paint and display it indefinitely. It can usually be toggled off or on to aid in situational awareness.
So, in dot point format;
The video RU MOD provided was of the unified (ie civilian) traffic control system.
That system conforms to most current computerised ATM systems found in EU, US, AU and many Asian countries.
The display of MH17 (and others ) on the video is that of PSR and SSR data coupled with Flight Plan (FPL) data
The coupling process fails at the time of the missile strike, as evidenced by the appearance of a square. Logically, the result of catastrophic system failure on the aircraft is that the transponder fails to squawk the required code anymore, forcing a decouple. what is left once the FPL decouples and the SSR data is gone due to transponder failure is the Primary Surveillance radar paint of MH17. This paint is co-located with the square from the Flight Plan, they diverge as the projected FPL position of MH17 moves away based on expected normal speed of a B777, from its actual (damage and falling wreckage) location as per the PSR
The radar paint that the RU MOD tries to describe as the phantom SU25 is in fact the MH17 primary paint of what is now falling wreckage
