It's just a loop that paints the contents at the end of each run, the 
loop looks like below. Since Finale nowadays buffers the screen contents 
before displaying it, the illusion is an animation. It basically work 
the same way as animations in game software.

for i = 1, loopcount do
     MovePageTexts(pagetexts)
     MoveNoteheads()
     ChangeScaryStaffLines(staffsystems)
     MoveMeasureNumbers(mnumregions)
     MoveTimeSignature()
     MoveClef()
     MoveExpressions()
     MoveHairpins()
     ZoomText()
     finenv.UI():RedrawDocument()
end
