I think you're correct.

Well, that depends on who's giving the representation.  In manuals for various instruction sets, some go big-endian (left-to-right index) and some go little-endian (right-to-left index/base-2-exponent).  I think ITU-T recommendations - and IEEE standards? - go little-endian, but, as you note, RFCs go big-endian (perhaps they do so just as they go big-endian for byte order).
