They disconnected the autopilot to descend more quickly to get back on the glidepath. They left the autothrottles connected which were in 'hold' mode at idle thrust. Normally they would provide speed protection in FLCH or VNAV modes and 'wake up' to keep the airplane from getting slow. When you disconnect the autopilot you lose that protection even though the autothrottle is still active. I just completed my annual sim training and we demoed this exact scenario so we could make sure we understood how that works. The way the autopilot and autothrottles interact isn't always obvious.
