What is the blend option in the layer weight node?

Question

What is purpose of the blend option in the layer weight node?
The documentation just says it "blends" between the first and second shader.

That said, it may already be answered here: http://blender.stackexchange.com/q/21690/599 — gandalf3, Mar 11 '17 at 07:12
I've now edited the documentation in question, hopefully I've made it a little more descriptive? — gandalf3, Mar 11 '17 at 11:45

It blends the output between all 0 and all 1. This can be most easily observed by plugging the output into an emission shader:

When used as the mix factor for a mix shader node, it will blend between all of one material or all of the other.

so it seems to me that it's equivalent to a mix node. Is that right? – Iamisti Oct 04 '18 at 10:23
@Iamisti In the sense that the blend weight is analogous to the mix factor, yes. – gandalf3 Oct 05 '18 at 00:15
