Find Search Items in vim [Possible VIM Error]

Question

I wanted to understand the behavior of the return path in vim, so I tried to mark the position of the statement. Suppose I have the contents of this file:

Foobar

Running this command :s/\(foo\)\@<!/♠ /g, I got:

♠ f ♠ o ♠ ob ♠ a ♠ r

Why don't I have at the end of the line? Is the anchor not considered a position in this case? ♠$

Instead, if I execute this command :%s/\(bar\)\@<=/♠ /g, I got:

Foobar ♠

Any explanation? and can anyone confirm this behavior?
