Can you link the description you mention? From what part of the world was this source from? I have seen articles from Europe where the two terms are used interchangeably, which could be the source of confusion. There is a clear distinction between the two framing types, at least here in the US.

In terms of "modern" timber framing that could be considered more finished than a bare frame of 2x6's, both still need enclosing. Depending on what method of layout, the timber used, hewn, sawn, s4s, sanded, oiled, or left naked with handling marks still in place, round timber, organic shapes, etc would also figure into how the frame could be classified.
