AIActivate reset function not working

Testing lgnpc I came across a script error reported by Openmw-CS, an unexpected name. (reset)

script snip - AIActivate "in_velothismall_ndoor_01_alusar", reset ; close door "in_velothismall_ndoor_01_alusar"->Lock 20

According to scripting for dummies reset is a valid entry though its use is not well documented.
