To be fair with Dozy, this "misinformation" comes from Airbus itself, as the manual states in one page that the use of manual trim will "freeze" autotrim, and somewhere else that the PRIMs do not fault when manual imputs are applied, but that the PRIMS will re-synchronize with the manual trim imputs, which have the priority over autotrim.
