I'd also prefer to see just one URL for each page. I've noticed that in other PP products, the link on the photo is different from the URL on the text. Both point to the same web page.
I'm sure Google can handle this, but why wouldn't you just point to one "master" URL? It would mean Google would spider half the URLs and get all the same content. That means less bandwidth, less crawling, etc. I guess that's how it's "better" ;-)
