Would it? Have you tested? or examine source code? or just guessed?
I quick look at rsync and du suggest that you only consider --one-file-system when looking at a directory - they assume files are in the same filesystem as their parent. I cannot promise that everything would work exactly as expected, but I suspect most things will..... though that might depend on your expectations.
