SSD: Does a CHGPF move the data off immediately?

Let's say you have a table with UNIT(*SSD). You also have smsetstayoffssd
set in SST. Now you do a CPYF or CRTDUPOBJ of that table for testing
reasons. You then do a CHGPF on the new object to change it from
UNIT(*SSD) to UNIT(*ANY). Is it immediately moved off of SSD or do you
have to run
STRASPBAL TYPE(*MP) ASP(1) TIMLMT(*NOMAX) SUBTYPE(*CALC)
or
STRASPBAL TYPE(*MP) ASP(1) TIMLMT(*NOMAX) SUBTYPE(*SSD)
afterwards to get the data moved off of the SSD's?

Hey, my SSD's are down from 65.8% full to 65.5% full today. Not initially
significant, but it does show stuff isn't growing (so smsetstayoffssd is
probably helping). I could hope that a coworker did some of those CHGPF's
on some tables and those got chucked.
