wither the checkpoint?

I have an esoteric question on checkpoints that I need answered. The Oracle8 Backup & Recovery manual, under the heading "Managing Checkpoints", states the following:

"A checkpoint identifies a redo log record such that all

changes prior to the change pointed to by the checkpoint

have been written to the datafiles by DBWn. "

The way this sentence is written, it sounds as if the specific change pointed to by the checkpoint has NOT been written to the datafiles. Is that really true? Does anyone know for sure. Can anyone point me to a reliable reference that clarifies this?
