Yes, you're right. That was phrased a bit haphazardly.
My point was that we can't just determine the typical time constant for a hormone's effect and run home with it since there are chemicals which have significantly lower time constants and some of them act as endocrine hormones as well.
Furthermore, an immediate feedback loop isn't the only possible way the body could play a role in cognition, though I suppose the OP is aware of this and was talking about moment-by-moment interaction with the body on purpose.
