Nah, continuing a task while trying to process something like this is something the vast majority of humans would do.
I remember a common repost on reddit. A female reporter in the 60s asked businessmen on the street about sexual harassment and if it was ok to touch their secretaries. The ones that would say it was ok shed start sexually harassing them and they had no fucking clue what to do.
They reacted the same way, trying to continue the interview but obviously uncomfortable (even tho they had just been flirting with the attractive reporter).
I'm a guy (a pretty big guy at that) and I've had women grope me out of nowhere during my bar days. It's a mindfuck, and you just kind of go on autopilot while you try to rationalize what's happening.
The woman's reaction in this video is completely normal.
