You know that this is only "half true" what you say. The path construction uses the CTM to fix up where the points have to be.
If you now invoke something like "stroke" it has to "enhance" the path to make it "substantial" and it will do this by CTM at this moment. As a "normal path" has no dimensions regarding how "thick" is a line, this is done at the moment the line is drawn. The "stroke" operator knows how thick the line has to be. So, this is wanted behavior. Nothing big to mention.
