Strange they have deactivated door 2 aft of the wing (was Door 3 position on A321ceo & earlier neos)
(new Airbus 321 Neo cabin flex options have a range of overwing exit and door 2 options to enable up to 235/240 pax)
In this Titan config Pax capacity would be limited to around 189 I think - not like a 220 seat 757
But I guess if they are doing Long Haul with this type then around 189 pax would vastly improve payload/fuel
