Your config will work, because it is NOT from the same domain. The short
name "bertand" in your config is considered a top domain by itself, so you
can dig bertand. (ending dot), but you can't dig bertand.your.dhcp.domain.

You will see the issue if you add the same domain in the cname config, eg:
cname=bertand.your.dhcp.domain,bert
