First let me say this is MY PERSONAL OBSERVATION 🙂

I don’t think all the words in Appendix 1 were chosen based on one single logic or plan.  I believe each word was reviewed and voted on and then added to the list (or not, as the case may have been).  It’s a list that you really just need to have available in a place where it’s easy to check if needed…and sometimes even when you are just curious if the word you are looking for might be on the list.

I’m sorry I can’t provide a better answer here.  I’ve tried and tried to apply my logic to that list and there is always an exception to my logic…so I have the list in a place I can use it frequently.
