your explanation would make sense only if there was a reduction in hydraulic pressure to the feel and centring actuator during forward control column displacement.

the FCOM says that the EFS module commands higher system pressure to the elevator feel and centring unit during a stall resulting in higher forward control column force.

In normal flight, feel is provided at higher airspeeds by the feel control computer which increases hydraulic pressure to the feel pressure hydraulic actuator which increases the centring force on the control column.

It appears from the FCOM, that the EFS module commands higher "forward control column force" at low airspeeds by increasing hydraulic system pressure to the feel and centring unit.

Could it be poorly worded or do they really mean that centring force is increased at high AoA or are we actually talking about an increase in forward control column force?

I agree with nick14, i think what they mean by the term "forward control column force" is in fact "aft column displacement feel force" but as with everything in the manuals, it is too condensed to make any sense except to the person who wrote it.
