Yes, that should be the case.  The ddns-hostname option is a pick() by
default, but if configured either in global or lower scopes those configs
should take precedence.  One experiment might be to set ddns-hostname in
the global scope to something obviously configured by yourself (so there
is no backup pick()).

Is it possible that these clients aren't matching any host entry
for some reason?
