Why is superheated steam used in turbines since according to Gibbs‘ free energy formula, at higher temperature, the ability to produce work is lowered?

So Gibbs‘ free energy is the maximum reversible work that can be produced in a thermodynamic system at constant P and T, and according to the formula, higher T means lower ΔG. Then why is Superheated steam used as means to produce work? Or am I looking at it wrong?

Because when the steam does work by moving the rotor of the turbine it lowers the pressure and temperature of the steam. You can think of it as a kind of temperature “buffer” so that the steam does not condense as it goes through a large turbine because water will damage the blades in a turbine.
