Yes it does. I chose a wind speed and direction that produced a match between the calculated Mach and the recorded Mach pior to the airplane going to very large AoA, keeping an eye on the wind recorded on the DFDR. One has to keep in mind that the DFDR wind is obtained by comparing IRU- or GPS-based groundspeed to the ADR-derived airspeed, and also that wind speed and direction may change in the interval shown.
