It seems to me that the effect is also intensified due to the fact that the outer corner of the eye itself has slightly changed.
In addition to the thickness of the eyelashes, their location has also shifted slightly downward in this new outer corner, which further enhances the doll effect that the author wrote about. This doesn't look like proper eyelash placement at all. The previous option looks much more natural, so I understand why many people are upset by the thickness of their new lashes.
