It says that if both `from' and `to' arguments link to the same
existing file, rename() shall return successfully and perform no
further action.

In the msdosfs rename("a", "A") case, `you lose' due to the rename()
semantics, but OTOH msdosfs can't conform to POSIX anyhow since it's
case-insensitive, whereas POSIX requires case-sensitivity.
