The mechanism allows a single Confirmation with Multiple Delivery Dates to operate as a series of discrete Transactions, each with its own separate Delivery Date.
As to the precise consequence, or intended consequence they were driving at: perhaps seeing as Disruptions tend to be Delivery Date-dependent, should there be a Suspension Event or some such thing on one Delivery Date, that is unresolved and, God forbid, graduates into a Continuing Suspension Event or a “then I woke up and it was all a dream” Event, it only cancels scheduled deliveries and payments on that part of the multi-Delivery Date Transaction that is actually affected, so each of the other micro-Transactions can carry on unaffected.
