Yes, I can also confirm that.

How do you reproduce that?

I think I cannot reproduce it. If I copy a cache file from
/var/cache/fontconfig to the appropriate font directory, rename it to
fonts.cache-2 and then touch that font directory, "fc-cache -v"
correctly removes the cache file in the directory and
updates the cache file in /var/cache/fontconfig.

I tried to make the font directory readonly by adding a
font directory to a readonly partition to make it impossible
for fontconfig to remove the cache file in the directory.
But even in that case it seems to work correctly:
