We're talking about the use of the word Knight versus Order.
There's no discrepancy there at all; those are just two different ways of saying the same thing. A society or fellowship of knights is known as a chivalric order
, or a military order
, depending on its nature and purpose. So "Jedi Order" would simply be a term for the society of Jedi Knights. I was just remarking that it seemed odd that the actual word
"Knight" wasn't being appended to "Jedi" as much, if at all, in recent years as it was in the past. But that's just about vocabulary usage, not the nature of the organization.
