Would you post that in the Wiki discussion?

It's different, unfortunately.  It's set by the first DTML method or
document that sets up the namespace.  Most people don't know about it,
which is good because it's a clean way to shoot yourself in the foot.

Jim has a point on the binding issue though.  Even better than "_.self"
is just "self", which should be possible (and reliable) with method
binding.  We don't want to create a new interface that's deprecated the
