Question about "one Frame per household"

So I think it's been discussed that if two different accounts order a Frame for the same address, lottery tickets of both accounts will be voided. Is that true?

My question comes from the strategy that many of you are going to use, entering the lottery for both SKU (1TB and 256GB) and then purchasing the one that would get to you first. But wouldn't that be "against the rules"? In the sense that you're trying to purchase 2 Frames for the same household
