Finish incomplete revert of ec63622c0.

Finish incomplete revert of ec63622c0. The code change this made might well be fine to keep, but the comment justifying it by reference to self-join removal isn't. Let's just go back to the status quo ante, pending a more thorough review/redesign of SJE. (I found this by grepping to see if any references to self-join removal remained in the tree.)
