Martin,

Possibly the hit might be the same, but possibly not.  An organization
that requires a second /48 from their upstream might get one that can't
be aggregated with the previous one.  It is my understanding that ARIN
is attempting to structure their assignments so that if such growth
occurs in PI space, it is likely (though not guaranteed) that the
network will get a subsequent allocation that can be aggregated with the
first.
