Here is a related issue (I think) that might shed some light. I am using
CentOS 7.3 and samba 4.4.5. Dynamic registration of workstation addresses
would work for a while and then stop working. I finally realized it stopped
working after log rotation. The CentOS logrotate for named runs the
following command after rotating the log file.

systemctl reload named.service

I disabled the rotation for named and now my dynamic updates don't break.
So I think you are right that the "reload" breaks something. "Restart"
works fine.
