Strange behaviour when clicking back

I have used this plugin and everything works fine but it annoys me a bit when your going through a list and loading more excerpts – and then click on one – read the story – and go back – you have to start from the top of the list again and load all the excerpts once again

is there anyway this can be prevented?

can be tested on your own demopage (see attached)
