It isn't. It's the A321LR.
There's come confusion here but you are technically correct.
The A321NEO is the updated version of the A321. The A321LR is the long range version of the A321NEO. It is sometimes referred to as the A321NEO LR.
CS-TXA, B, C and the future ones are the only TP A321's doing the long hauls across the pond. These are all A321LR's.
