Yes. Physicists have confused negative work and positive work. The 'en' in energy is 'input' or energy is 'work/ergs in'. When you set a heavy bag down you are letting work out. Lifting a bag against gravity is putting work in, dropping a bag with gravity is getting work out.
This is an error that started around 1900 when Physicists like Maxwell defined Energy as displacing an object in the direction of the force. This definition is an error, displacing an object against the force requires putting ergs in, energy. Displacing an object in the direction of the force is exergy, work out, like dropping a rock is work out, lifting a rock is work in.
