I feel this is dead herring!

If the TR Pitch reduces (reduction of effective thrust) drag reduces accordingly. This would momentarily cause the NR to increase as now power available exceeds power demand for Nr Nominal 100%. However, the FADECS would sort this out really quickly. In any case, a slight momentary increase in NR will not correspond to an immediate and somewhat sustained climb.

Other than that I cannot see any other correlation between the Yaw Channel (failed) and the collective moving involuntarily unless the mixing unit was somehow stuffed.
