I think the point is that the data Larian has on this system is misleading since although you technically had the option not to play an origin character, the non origin option was so lame and lacking that no one wanted to play it. If this is the reason Larian think the system is great than they drew the wrong conclusions from the data
I have some doubts, it is not that this data is analyzed by a random person in the company (at least I hope). When analyzing such a large amount of data, they certainly employ specialists in this field. They would have to be terribly removed from reality for the team not to take into account such an eventuality. Especially since it is not a far-fetched theory.
Of course, there is a chance that it did, but I would say it is quite small.
