Yes, basically right, here's the DS-free delegation:

    tools.ietf.org.         NS      gamay.levkowetz.com.
    tools.ietf.org.         NS      zinfandel.levkowetz.com.
    tools.ietf.org.         NS      merlot.levkowetz.com.
    tools.ietf.org.         NSEC    trac.ietf.org. NS RRSIG NSEC
    tools.ietf.org.         RRSIG   NSEC 5 3 1800 20170308083312 20160308073501 
40452 ietf.org. <sig>

The thing one might quibble about is the IMHO much too long RRSIG
validity interval.  One year signatures are rather long.  With this
signature in hand, an attacker can deny any signature for tools.ietf.org
until March 2017 even if the zone were signed tomorrow.
