No, the data that is available for download from FlightAware and FR24, while it certainly requires care in interpreting, is what the aircraft was sending (with a couple of caveats that aren't relevant here) and is independent of any prediction algorithms.
One thing that sticks out from the plot is that, aside from the vertical excursions, the last five minutes or so before the plot stops consist of two minutes of dead straight flight followed by two and a half minutes of continuous small track changes. I'll leave it to other to speculate on the significance of that.
