I do not see that this is expected behavior, and switching off warnings is generally not a good idea.
It may be that this does not cause any problems, but it is clear that this raises questions.
What I find worse is that even only opening a file on the iPad (without editing or saving it) gives the same warning.
Dorico-for-iPad therefore overwrites unsolicited files and despite the fact that Daniel Spreadbury indicates that I don’t have to worry about this, I don’t like this.
