`Download` vs `Make Available Offline` in Box Drive? and archived Box Sync containing copies of everything?

Hi,

I recently got a new computer (MacOS Sonoma 14.5) and updated from Box Sync (what I used in the past) to Box Drive.

1. What is the difference between pressing the cloud icon to download something in `Box Drive` (which I did for all top level folders), vs right-clicking in Finder and clicking `make available offline` for each folder? The wording between the seem redundant

2. When I installed Box Drive, as expected, it uninstalled Box Sync. However, the archive folder it made, seems to be identical to the Box Drive folder; they both contain everything. Is this expected behavior?
