Think about Emacs as a word processor which can save the formatting and
typeface of characters in the buffer's file. In that case, when a
typeface changes, the file's contents change. The fact that Emacs
currently doesn't save faces in the file is mostly irrelevant; it could
start doing that in the future, if, for example, compilers will begin to
accept XML files as sources.
Or look at it this way: when the program's source is visited by Emacs in
another session, it's again fontified as it was before. For all
practical purposes, the face was ``saved and restored''; the fact that it
didn't come from the file is something that you know about Emacs's
internal operation, that's all.
