I wasn't sure about the translations of the sins (they seem to be somewhat different in english and japanese), but the poster also put the english names of the items they convert to in Katakana and those items are definitely what he wrote.
I'm thinking it's bullshit myself, too, but I wouldn't put it past SE to ninja this either.
More simply, according to the story:
AV raped their tanks with DA criticals, then used Call Wyvern
There was chaos, so they didn't bother to use any 2hs
The second 2h AV used was Manafont
The list of 2hs after are the 2hs the players used against AV during it's Manafont
It never used Meteor during Manafont, and never used Manafont, Chainspell, Benediction or Call Wyvern again.
