No, 'span' covers the appearance of the bar line *between* staves.
The first argument (']' in your example) is used for bar lines mid-line.

I admit that the bar line interface and its documentation are far from
being perfect. The what-you-see-is-what-you-get approach seems to
confuse quite a lot of users.

There was some discussion about making the interface more user-friendly
and allow for aliases, but there is no final consensus yet IIRC.
Moreover, the problem with repeat sections, for example

c4 c c c \bar "||"
\break
\repeat volta 2 { d4 d d d }

was not covered at all yet.
