"Compress item" inside Time Machine backup

Trying to compress (by right-click + "Compress item") an item inside a Time Machine drive's /Volumes/drive_name/mac_name/Latest folder will put the resulting .zip file on /Users/user_name/Desktop on the host computer.

This of course does not happen with other external drives not used as Time Machine backups.

Why does this happen? And how does it work, under the hood, the process of detecting that I'm trying to create a new compressed file in a Time Machine drive and of making a copy of the new compressed item to ~/Desktop?
