Why should I not use this to back up my vault?

Found this warning in the plugin:

Warning
Do not use this plugin to sync or save your Obsidian Vault!
Avoid opening the converted files from your repository in Obsidian!

[Mara-Li]

Because the plugin does some edit to your file, and it can create some cyclic edition and broke path with Obsidian

Found YAOS (stands for Yet Another Obsidian Synchronizer) plugin for this - thanks!
