Actually this could be a good question to ask about the ISO list in
general.   Ie did the ISO consider the potential for confusion when
selecting the two letter codes?

Actually I have read some research to indicate that humans are better
able to distinguish differences in short strings rather than long
strings.

E.g humans can spot the difference between "to" and "tom" relatively
easily, but not necessarily between "licence" and "license" .
