Confusion about "writing to one side of a partition"

In section 8. why is CAP true it says

The basic idea is that if a client writes to one side of a partition, any reads that go to the other side of that partition can't possibly know about the most recent write.

but this is confusing to me. Because in section 7. What is a partition a partition is defined as

A partition is when the network fails to deliver some messages to one or more nodes by losing them (not by delaying them - eventual delivery is not a partition).
