Hilton and Advertising E-Mails

I've recently had a look through my gmail filters and noticed the Hilton one is IMO excessive...

Matches: from: (embassysuitehoteldeals@h1.hilton.com OR hhonors@h1.hiltonhhonors.com OR embassysuitedeals@h1.hilton.com OR hiltongardeninn@h1.hilton.com OR HiltonHHonors@h1.hilton.com OR hiltonvip@h1.hilton.com OR homewoodsuites@h1.hilton.com OR embassysuiteshoteldeals@h1.hilton.com OR WaldorfAstoria@h1.hilton.com OR hiltonhotels@h1.hilton.com OR embassysuitesbyhilton@h1.hilton.com OR noreply@h1.hilton.com)
Do this: Apply label "Adverts", Never send it to Spam, Never mark it as important, Categorize as Promotions

Is there ANY reason, other than "lets-try-to-evade-filters-through-a-crapton-of-addresses", to use that many different email addresses to advertise?
