Additional technical notes: (mostly) FCOM DSC-22_30-40-90-20

During a G/A the FD limits for SRS vertical mode are 18° or 22,5°in case of a wind shear alert. The target speed for which the airplane will pitch for becoming:
- no lower than Vapp (net of any GS-mini adjustments)
- no higher than Vls+25 kt
+ commonly in-between, set to the speed value present at the moment of TO/GA engagement

Pure speculation: If the crew hit a small rotor with a momentary tailwind burst (or loss of headwind) resulting in
- a drop of IAS close to the Vapp (net) value or even below
- trigger of reactive wind-shear alert
+ the FD command would go for quite a low-speed target up to 22,5 deg NU, which the NEO engines at TOGA thrust could deliver efficiently. With an airshow-like climb.

I still think the overpitch is some sort of camera effect, it looks unusual only for a half second before it is clear the airplane is flying over the viewpoint.
