Good point, John. I happened across this APAR, addressing the issue:
IX82232: RECONSTRUCTION DOES NOT OCCUR DURING MOVE DATA
Move data by design does not perform reconstruction
of aggregates with empty space. Although this was
discussed during design, it was decided to only
perform reconstruction during reclamation. A major
reason for this decision was performance as
reconstruction of aggregates requires additional
overhead that move data does not; hence requires
additional time to complete.
