Actually I'm pretty sure this is post AvX7. They do a horrible job of it, but if you look carefully you'll see that Spiderwoman is not among those in Strange's teleporting spell. And Hawkeye got Phoenix-burned and left there too. Later in the issue Sunspot throws Cage into the Siege Courageous.

Either that was a trick for the simulation or it's a reference to this occuring after the Thor/Emma fight in VS#4



Unlike the usual 3-6 issue stories which usually just span a full day, Marvel has to have this event span weeks to make the Phoenix-Five's transformation of the Earth more realistic. (as tough as that is)
