This is a very good question.. In the section of the video on automatic form layout it is strongly implied that the auto-layout is driven by semantic inference of the column names. I see this easily breaking -- anyone who's ever inherited a production database knows that column names are often cryptic or context specific.

Also makes me wonder how well that system handles databases with non-English identifiers?
