If the aircraft was heading upwards when the 2600' and 100kt were recorded,
The AAIB interim report states that the 2600' figure came from the radar trace, and then further on in the report mentions cockpit imaging and the 100 knot minimum speed figure - implying (to my mind) that the 100 knots was derived from cockpit imagery that was recovered. What I don't see is the AAIB saying that it was 2600' and 100 knots at the same time.
