This 'heat soak' stuff is a load of balony - it's been around for years! Truth is that an old starter may have poor windings and/or clapped out brushes. Of course a new starter will solve it. One of the commonest causes of poor hot starting is lack of valve clearance, either becuase the tappets are poorly adjusted or they have closed up due to lack of maintenance. What happens is that the tappets hold the valves slightly off their seats when the engine is hot, giving low compression and poor starting. I take it you try to start it with your foot down on the floor - that's the best way to get a hot engine going.
