You would have been right if the entire filesystem were to be immutable. However, for Fedora Atomic, /var and /etc are writable. Thankfully so, as most people wouldn't want a totally locked down operating system. Heck, no general-purpose distro (or OS otherwise) tries to achieve that level of immutability by default.
