What Kay Pam said is correct. AoA has priority over other protections. So if high speed protection triggers an aggressive pitch up and it may end in alpha prot. There was an airprox incident over the Atlantic between the A340 and A330 where due to turbulence and copilot merely disconnecting the AP but not pushing the stick caused the aircraft to rapidly climb through the altitude of the other Aircraft. Perhaps that triggered the change in ELAC with a new software.
