It seems a lot less likely that someone would write a predictive algorithm which would "predict" an airplane maintaining 5000 ft MSL and 300 knots, plus or minus random excursions either side of both parameters, for 6-ish minutes, when in fact the airplane did something completely different.
Yes Flightradar does predict the path of flights when the data stops in real time, but only for a minute or so, then the plane usually stops at that point, then a little while latter it disappears. The tracking line then reverts back to the actual data received & removes the estimated components.
When you view the flight later or download the raw flight data it is only the received data, there is no estimated flight data.
