As a non-native speaker I say that there is a huge difference between speaking/writing fluent English and doing this in a way that satisfies "unwritten cultural conventions".

For my English, for example, native speakers tend to say that it is actually quite correct, but I have a tendency to use words in a specific way in which few native speaker would use them.

I am a non-native english speaker too; I guess I bristle at the the reading that this man isn't in control of his english when he writes with obvious proficiency, a reading I suspect, would not at all be in question were his name John Foster Edwards, or Henry Wickham or whatever Anglo-Saxon name you wish to replace his name with.

I see your point though. I think he does use words in ways that native speakers do not use, but in his anecdotes -- I think he's actually playing up his Chineseness for the comic effect, and he's very much aware of what's happening.
