The Avatar Spirit is triggered by intense emotion, like anger or fear. Korra was close to those emotions, especially fear, when facing Amon. So, that would have triggered her spiritual side and caused a pathway for Aang to communicate, even slightly. As Korra pointed out, Aang was warning Korra about Tarrlok.

They do seem to be setting up a Yakone/Amon connection, but only time will tell what the truth is.
