Why are these called 5 way binding posts? I count four!

You could always unscrew the terminal, slip a ring connector on, and put it back.  Then you have 5 ways.

I use it a 5th way, and I like it best. Will send pics soon.

Wow! Is EBM making a comeback under an assumed name?

I don't know who EBM is, this is my first time ever on here. Stumbled on this looking for other info. But I'll try to upload a picture of the way I load binding posts.
