FWIW, I'm sticking with Neph's or TDM's 6.0.4.5 builds until I hear from them that the copy on the CWM site is good... Or Yoinx's TWRP build. If the CWM version jumps on the site, I'll test it out, but I'm waiting until then.
I know this doesn't answer your question, but wanted to let you know you're not alone in your curiosity/confusion.
