you mean

\global\advanceby\makeupheight
   \dimexpr-\bottomdistance-\bottomheight-\scratchdimen\relax

becomes

\global\advanceby\makeupheight
   \dimexpr-\topdistance-\topheight-\scratchdimen\relax

but the top values are actually in scratchdimen so

\global\advanceby\makeupheight
   \dimexpr-\topdistance-\topheight-\topspace-\topheight-\topdistance\relax

or

\global\advanceby\makeupheight
   \dimexpr-2\topdistance-2\topheight-\topspace\relax

which is wrong, so the question is: what is the issue you try to fix
