NDD 1.0 does not know about alias records. If you have created aliases
on a volume, nothing short of reinitialization will make NDD 1.0 happy
with it.

That is a gross exaggeration. To my knowledge, the only thing that was
added to HFS data structures on disk are alias records, which are
ignored by previous version of HFS.
 
If the the directory structure were "completely different"
6.x-and-earlier systems would hardly be able read 7.0 volumes.
