Slaves send NOTIFYs to all authoritative name servers except the one
in the MNAME field by default.  To really tune your NOTIFY setup,
you could set the "superslave" to use "notify explicit" and send NOTIFY
messages only to the "subslave."  Then you'd set "notify no" on all slaves
that weren't themselves masters.

This is, by the way, in the cookbook.  ;-)
