this is not true, people still care if you are a reseller.
Some people will not host with you if you are a reseller as you have no control over the server if issue occur.
Most savvy people will have their own VPS and would not have reseller accounts, so if you have a reseller some do not want clients to know they are reselling your services, so using a whitelabel hostname help them out as not general users will not dig deep to find the real server provider.
It also helps if you have several servers as you can run all the hostnames off the same domain without you main sites account being full of subdomains
