I can understand (and im sure Ron would) what the guest said. However, I think that the similarity between some of his songs is purely because he has found several styles which suit his voice and go down well. I do see what you mean. But the thing is, he has written enough songs that it doesnt matter and when he is doing a set he usually makes it so that the songs which are similar are as far away from each other as possible, or just doesnt have two similar songs in a set.
