Perhaps the "wording" used in blockchain.info could be better (i.e. "double-spend attempt" vs. "double-spend").

Of course until at least 1 confirmation has occurred it is impossible for them to identify which one is the one that "will go through" (apart from perhaps guess by looking at the tx fee which would not have helped in this case - but they should probably change the wording after x confirmations as the other is never going to confirm then).

Note that https://blockchain.info/tx-index/65484044 has 47 confirmations (so it is a *real* tx) whereas https://blockchain.info/tx-index/65484042 has no confirmations (and is never going to get any unless Bitcoin has a major disaster).
