Therein lies my concern. If programming a bot I'd be following the rules of engagement in regards to the cascade. But, this is a Robots Directive and I'm 50/50.
Would it stop at the first directive and go no further?
Or, would it continue to index the entire <head></head> and honor the second directive which would override the first from a cascading perspective?
A little OT, I can confirm that G does not honor noindex, nofollow, noarchive. All three directives combined in that sequence. It will noarchive.
