"Watch this article" and "View article" are clearly wrong and need to be changed. We have a definition for what we consider to be an article and that doesn't include any namespaced pages and also doesn't include many pages in the article:namespace. "Watch this page" is correct in all cases and should be used. "View subject page" is also correct in all cases and should be used.
If this nomenclature we use is internally self-inconsistent then the definitions we use for things become ambiguous and may become useless.
