Hi Rebecca,
That is correct, as you can imagine Views are critical to creating reports, if a view is broken, the reports are essentially broken.
When reports are built it's assumed that the view itself will not be removed, you can modify the view, though you cannot remove items that are in use by existing reports.
It's just a way to make sure reports are not destroyed by view modifications.
