Yes. Yes you are.

Going back to that thing about the language on the can, Ymir was wandering as a Titan for 60 years. It's very possible that the can writing was just very old, or written in a language from the time she grew up in Marley. The language may just have been very old and no longer spoken while Reiner was growing up.
