Are there really no situations where a fix script will run automatically? Everything I read says it can't be done, but I'm seeing something to the contrary.

I am developing a scoped application and when I load it into a new instance from Studio via a source control import, I can see that my fix script was run without my   having to navigate to the Fix Scripts list and run it manually.

I can see log updates and record updates that only the fix script can perform.

What's even more interesting is that I have a second fix script that isn't run automatically, and as far as I can tell, the only difference in the settings is that the Run Once value is true. I've deleted the app a few times off the instance and reloaded it, so I wonder if it literally ran once during the first load and won't for any future loads.
