No, you didn't dream it. My Empeg does this too.
It seems the top edges of the handle (the part where it hinges onto the Empeg) are square in form other than round. Because of this, when the handle is pulled forward, these top edges push the Empeg 1-2mm out of the sled. Usually just far enough for the wire loom connector on the back of the sled to let go of the Empeg.

I don' t know if it was inteded this way or not, but it works quite well. Because of this I never have to put any brute force on it and the Empeg just slides right out.
