doesn't he just mean that he uses RSYNC to that the mirror and the source are in current sync rather than staggered as would happen in a ndmpcopy or anything other backup sort of operation?

Then, during the week run rsync's with --delete to keep things 
nicely in sync.  This is something ndmpcopy can't do (I think).... 
if you do a level 0 + level 1 you won't get deletes.  

No, that's completely false. ndmpcopy uses the same underlying apparatus
as other ndmp operations (or straight dump / restore, for that matter).
Deletions and renamings are dealt with correctly in incremental dumps
and restores: they wouldn't be much use if they weren't.
