Thats great!  Nginx should pass the hostname in the browser to apache,
so there should not be a need explicitly set the hostname like that.
However, if you are browsing using http://dbeach.local/dataset (or
using the ip address) it will pass the hostname as dbeach.local and
may cause errors.  So setting it explicitly will help with local
testing.  I can not think of anything else that would cause that
inconsistency.

Thanks
