Three might be on the edge for a human inspection. But since so many CMS autogenerate the filepath from the title, I doub't that you would run into a problem with Googl if it only happens once in a while. You also won't get an advantage from the repetition, IMO.
I started using a SEO component which turns my page titles into really long URLs. Shortly afterwards my SERP imrpoved considerably. It certainly doesn't seem to hurt. In my case I'm pretty sure it helped.
