Yes, this is misleading, and I've corrected it on the (now rewritten) page.
To be accurate, though, what you're doing there is not changing the DAR of
the video itself, but creating a new video stream with a different DAR.
For example, when you apply letterboxing to a 16:9 video, you're creating a
new video (with a DAR of 4:3) that happens to contain the old video (in its
original DAR of 16:9) sandwiched between black borders.
