No, as you can see in the image I've attached it is effective in a \layout
block.

It's there:
*The \paper variables that can appear in a \layout block are:*
*line-width, ragged-right and ragged-last (see \paper variables for widths
and margins)*
*indent and short-indent (see \paper variables for shifts and indents)*
*system-count (see \paper variables for line breaking) *
If I put line-width in a \paper block, the systems are automatically
centered.
So, unless it's a bug, I suggest adding a sentence to the one I previously
quoted:
If line-width is set, and both left-margin and right-margin are unset, then
the margins will be updated to center the systems on the page automatically.
*Note that line-width must be in a \paper block, the margins won't be
updated if line-width is set in the \layout block.*
