It's a feature: Emacs remembers the file's attributes from the time
you visited it, which was before it was made writable.  Either
checkout the file _before_ visiting it, or "M-x revert-buffer RET"
after you checkout it, if Emacs is already visiting the file.

C-x C-q only makes the buffer modifiable, but it does nothing to the
file's attributes on disk, as Emacs remembers them.

Anyway, thank you for your report.
