The 42 day lock @ Enom is more of an escrow hold than a redemption period.
From their FAQ -
What is "Auction Lock" and why is it placed on Pre-Release domain names supplied by eNom?
If a Pre-Release domain name is supplied by eNom, upon receipt of your auction payment the domain enters an Escrow Holding Period known as Auction Lock. This holding period lasts for 42 days following the completion of the auction. During this period, the domain cannot be transferred, the WHOIS cannot be updated or changed to anyone other than the successful bidder, nor can you push the domain to another account.
If for some reason the domain is taken back they would be forced to provide a refund.
