Sorry but it doesn't make sense. How would the computer "simply displace the elevators to a new "null position" and "trim the new attitude" without changing the THS setting? When trim is activated manually, autotrim is frozen, can't displace anything anymore. If one is trimming manually, he's overiding autotrimming and computers would resynchronise with manual imputs after this point.
