Correct, this is a desired behaviour in our opinion, too.

I thought that Pre-Publication Method is feasible only for ZSK
rollovers? If we publish the new DS record in the parent zone and
someone queries it before we have activated the new KSK, he or she is
unable to validate the DNSKEY RRset as the DNSKEY RRset is still signed
with the old KSK but the DS points to the new KSK. Or is it assumed that
the parent zone supports double DS records?
