Let me recapitulate.

If we have "display: block" and "content: none",
the model is <div/> (which is the same as 
<div></div>).

If we have "display: block" and "content: ''", the
model is <div><span/></div>

Doesn't it strike you odd that by inserting the
content of <div></div> with a stylesheet, I don't
get the same rendering as by using the exact same
string as its content in the markup?

Anyways, to go on...

So you agree that by default, :before/:after exist
as inline boxes.

background-image takes type 'mixed content replaced content'?
