"SLO allows uploading many objects concurrently and afterwards download them as a single object." .. while this is true, I don't think it conveys the feature. SLO is about uploading large objects. So It allows splitting a large object into many smaller objects, uploading these and then treat the result as a single large object.
Doc text looks fine to me. Moving it to verified.
