Clarify what happens in relationship fixup

[adisazhar123]

In reference to this sentence

Note that blog will also be inserted into the database because it is a new entity that is referenced by the navigation property of an entity that is already tracked by the context (post).

What happens to the old Blog entity? Let's say that only the current post is in the collection of Blog.Posts, and I change the current post's blog to a new Blog entity. Will the old blog entity be removed from DB? Do I have to explicitly call Remove function?

I guess the rational behaviour is to not deleting the previous blog (because e.g., it may have other posts), though I'm not sure.
