It was a cute little video intended to show off Larian in a human light. One of the things they're most praised about online for BG3 is the way they've given the player so many avenues and choices. Plenty of players like that they can skip Shadowheart and see her show up later at the druid's grove.
This video showcases that work. It does so in a somewhat humble and humorous way, illustrating the size of the workload they've tackled while admitting that they still have to rely on the occasional clumsy and heavy handed scene if the player actively ignores every other obvious path.
What I suspect they weren't doing was asking for advice from every armchair game designer on the planet.
