From the report pages 21/22:
At 15 h 45 min 40 s, the control law for pitch passed from direct to alternate. The bank angle reached a maximum of 59° to the left and the normal load factor dropped below 0.5 g.
At 15 h 45 min 50 s, the normal load factor exceeded 0.5 g.
It may be that the only load factor readout is above/below 0.5g - no info.

I'm really surprised that it was constant for so long (30 secs).
Rusty maths but I suspect you have calculated an average value over time, not a constant value - also the pitch rates that the a/c experienced in the final 15 seconds are not consistent with constant 0.57g. I agree about the parabola over the top - typical ultra-low-speed behaviour.
