I don't think the description is wrong. It really means the height and states that the default height is equal to bar's width.

For me that's unclear. In the paramter list it's length (why not width then):

and in the description:

Yep, the length in the option synopsis may be a bit misleading, but just a little since it's neither width nor height so it should not be confusing either.
