I don't know, looks like a distinction without much of a difference to me.
When you get right down too it--China was seen as the "place" to go to gain skill in martial arts.
And pretty much everyone that either was or became "someone" in Okinawan martial arts circles is linked to China in some regard.
They either went there personally or trained under someone who did.
So I think its kinda questionable to use words like "foreign" or "native" in this context.
Hard to say exactly which is what--or how much or to what degree.
You could also read the passage as more a case of "marketing"---the passage talks about ways to "reflect" given traits--ie focus/emp certain aspects and possibly deflect focus on others.
I tend to view the "old-timers" as a pretty savy bunch all the way around.
Certainly they were smart and canny enough to know how best to appeal to certain people/groups/viewers etc.
