Firstly, no, it's not gone forever. It remains in your onedrive recycling bin for a month. Secondly, that behavior makes sense. One drive is a mirror of your synced folders. If you just want to not have the file downloaded in your computer, just right click on the file and select "free up space".

It's so obvious!

It is. Another indicator you get is a status icon next to each file telling you if the file is permanently or temporarily (meaning it will get auto-deleted locally if you don't use it) dowloaded to your pc or if it's only on the cloud.

Oh, and you also get a prompt when you delete a file letting you know that it will be deleted from onedrive as well but it will still be in the recycling bin for a while. The only way to not get that prompt is to tick a box to not get reminded again.

Microsoft software has a lot of flaws but this isn't one of them.
