I assume it is because the negative offset reduces the skyline of the broken (following) system, which allows the spacing engine to raise that system.

Hi all, (Happy New Year!) Is there a logical reason that for most tweaks negative extra-offset values move the associated grob vertically lower on the page, but with NonMusicalPaperColumn.line-break-system-details it moves the associated system *higher* on the page? I offer it would be better if extra-offset had a consistent behaviour/effect. Thanks, Kieren.
