They do similar things, but in different ways.

The SOA refresh interval tells secondary servers how often to check with
the master for zone file updates. In the absence of notifications, this
controls how long it will take before updates are noticed.

Notifies largely negate the refresh interval since they allow the master
to tell the slaves when an update has been made. However, notifies are
pushed out and there is no mechanism to ensure they're delivered
successfully, so the refresh interval still needs to be set to something
sane to handle the case of a lost notify.
