Tumbleweed snapper snapshots order

Yes. Snapshots are frozen states of the root subvolume at some past point in time. All changes go into the main root subvolume which does not change unless you perform rollback. And “back” in the “rollback” refers to the point-in-time, not to the snapshot numbers which are more or less irrelevant.
