Hi,

If the PF had let go the stick the airplane likely would have gently,
Methink if the PF let go the stick (auto reposition in neutral position) this will not help as the commands (mobile surfaces) will stay in the position they were set (climb .. THS climb .. etc..) and the aircraft will eventually stall
Push on the stick is necessary to move again the mobile surfaces for stop (or reduce) the climb or for go down
