Gums,
I agree that 1g can't be right.
If the aircraft is accelerating, turning or slowing, then the seat-of-the-pants force will change in magnitude or direction from its value sitting on the ground.
It has to, as the aircraft needs to push your straps/trousers to change your velocity so that you move along with it.
In a steady climb, descent or turn the seat-of-pants force is constant, but different from 1g. In a steady climb or descent it's 1g directed a little forward or back; in a steady banked turn it's about 1/cos(bank angle) directly up out of the seat. At 30 degrees that would make you feel about 15% heavy.
Perhaps "maintains 1g" is shorthand for "Taking your hands off signals the FBW system to keep constant the seat-of-pants forces that are currently being experienced."
