It would be totally appropriate to move the manual trim in both directions slightly if you suspected it was jammed. It probably moved nose down only, and not nose up.
Another thing, the .2 degrees is within the error margin of the recording system, the FO might not have moved the trim at all, and this is simply instrumentation.
