Yep exactly. The issue is not so much sharing of your work (with a link back to your site), but taking your work and passing it off as your own is completely different kettle of fish.

Does anyone actually change their sharing settings on flickr by the way? I've got Getty images licencing enabled, but also creative commons licensed as long as the image isn't modified in any way.
