I don't think in my friend's case this is true. I think it is just habit. I believe he has Google as his home page, so whenever he visits me and he wants to show me something on the web, he first goes to Google (then wants to know why Google isn't my home page), then do whatever he wants from there. I asked him why he does that but he doesn't really know why either - there is no real thought put into it.
