Man, I can't believe that happened... I worked at the Genius Bar for a little while, and it was always standard policy to make the customer push the factory reset on their phone so they knew exactly what they were doing and were responsible for the data. I can't imagine that policy has changed so that was a major screwup...
Yeah, @bryan-imhoff. That's exactly what I was thinking and as I mentioned in the post, this if the FOURTH iPhone X that this issue came up. Two replacement phones and a screen replacement. Every time [...previous to this] I was the one that had to erase all settings and data. I had to physically push the button. I was blindsided and black out angry. It's at least some closure in hearing you say that so I know this was a horrible human error.
