I could reiterate what Rob just mentioned. We can't confirm, but we can take your word for it that it doesn't appear elsewhere in the act. There is a difference between “personal”, on the one hand, and “private” or “non-commercial”, on the other. One place where that would definitely be apparent is the concept of “non-commercial” would appear to be much broader than the concept of “personal”. And it's “private” or “non-commercial”. So switching the words would have the effect of broadening the exception.
