This appears to raise the top system without moving anything else;
specifically, without moving the other systems upwards in proportion.
OTOH running LP a second time with smaller margins (and stealing
a page) redistributes the staves automatically. It also takes care
of page numbers etc.

(BTW it might sometimes be more tasteful to steal pages two by two,
ie as double spreads.)
