Wild (completely speculation) guess:

Maybe this is an artifact of "small file aggregation", where for many
operations *SM treats a block of files as an entity.  That is, *maybe*
QUERY VOL size is measuring aggregate size, whereas QUERY
OCCUP size is measuring unexpired data size. (Some of the
aggregates contain expired file data).
