Related questions
Why did Preview only change the first file?
Dragging into the sidebar edits that PDF. Use Export as PDF to save the combined file under a new name.
Can Finder change the order?
It follows the order of selection or names; rename files 1, 2, 3 to control it.
Are files uploaded?
No, all three methods work on your Mac.
