Worry more about the "honor" in your own practice than the "honorary" in some one else's rank.
Thats very nice, I like that.
Much further up, I noticed:
Somebody anonymous wrote:
It's particularly iritating when your kohai suddenly becomes your sempai right?
Don't confuse the sempai/kohai thing with the ranking thing. (Most of us in western dojos aren't doing the sempai/kohai thing, btw, even if we think we are)
If you have a kohai and that person is promoted above you, they don't become your sempai. They're still your kohai, they just happen to outrank you.
The Shihan to whom I look for inspiration, for example, has quite a few sempai whom he outranks. It makes for interesting politics.
