    I think that basically means the contractions that move the egg down the 'pipes' go into 'reverse' and the completed shelled egg moves back 'upstream' and it meets up with another yolk and the shelled egg gets encased wit the next yolk in another shelled egg. Not unheard of but not terribly common. It's more of a glitch and much more common with new layers while the reproductive system gets tuned up for the first time.

    That's a rather clumsy explanation and pretty much the same as the article you linked...but hope it helps.
