"State", as Tyler describes it, is a talkative high-energy emotional state caused by neurotransmitter saturation. He gives specific exercises to reach this saturation point, e.g. "unstifling" and otherwise doing things involving facing fears. "Get into state" is a core teaching of RSD. I have not heard them give the definition you just did.
However, that is still useful in this analysis: the fact you have a very different interpretation of "state" shows its groundings in metaphysics. He is not pinning down anything specific, else it would not be possible for us to have this conflict of interpretation. "State" therefore is very similar to saying something like "mojo". It is metaphysical, non-defined, and consequently cannot be relied upon as a consistent factor in your pickup. Imagine saying "I can't do pickup tonight because I don't have my mojo" and you will see how meaningless the statements become when trying to teach something.
