Not at all uncommon for that property. At the end of the day, the balance of power favors hotel owners and managers over Hilton Honors. If a property decided to designate two rooms as eligible for standard rewards and a year's worth of them sell out in a day, there's not a lot Hilton can do. And, if Hilton did decide to make a fuss, the hotel could very easily increase the point cost of a 'standard' reward by 20% to offset the cost of anybody using the pay for four, get five Honors reward.
