Doubled notifies should not be a problem; they're just discarded or NOOP's.
Make certain that you see a notify from the server you have in masters {};
directive -- the slave will by default discard notifies from servers not in
masters {}; (But also look at "allow-notify"). One idea; is the zone size
significant? It might be so that the notify arrives from S1 to S4 and is
processed before the zone has been properly transfered to S2.
