The game never specifies that Artorias went to New Londo.

It's fully possible it was cursed when he entered the Abyss, and then corrupted further when he was taken over by the Dark. According to Chester, there was a Primordial Serpent involved in Oolacile's fall aswell, which is likely how Artorias made the covenant.
