I think he is pretty clear that natural selection was not involved in the transition to complex life. That this was jump and not a gradual transition.
Personally, I am not a pan-selectionist. I tend to think that there is too much emphasis placed on selection. However, even those who do emphasize selection usually avoid talking in terms of "rely on natural selection."

I haven't read Lane's paper, so I'm going by your quotes from it.
The idea that one organism jumped inside another, leading to a sudden transition, is surely mistaken. There had to be a lot of mutual adaptation before that was possible, and natural selection would have been involved in that mutual adaptation.
If the point you are making is that endosymbiosis doesn't quite fit in the typical neo-Darwinist picture, then I agree with that. And most neo-Darwinists would probably also agree. I don't see that as a problem with evolution.
