Right now, just consider most of them to be vanilla bandits that follow that code of dress.

However, I would imagine that with the defeat of the Horde and the death of Khakhan those surviving Tuigan splintered into a lot subgroups. I could see one of those smaller groups still having an interest in the land of the Red Wizards and the place of one of their greatest victories. The whole affair could have made them more worldly and broadened their raiding territory.

I'm really not against the idea of them being used as Tuigan in a DM led event or (even)against some PCs role playing amongst themselves that the random encounter rider was actually a Tuigan. I loved that campaign! To see it have some kind of lasting impact upon Thay would be it's just reward.
