Of course the laser is tightly focused. That's pretty much one of the defining properties of laser devices. How else do you think the laser is heating the microprocessors in the video?
They shouldn't be focusing it to a point under any conditions. Whether it's as safe as it could be is a different question, of course. For instance, you'd like to think that the act of configuring it for a smaller beam footprint would reduce the power at the same time, as opposed to requiring a separate adjustment that might be overlooked by the operator. Would have been nice if the video had addressed that and other safety considerations, for sure.
A lot depends on the exact wavelength. 1400 nm and longer is much less worrisome than near-visible IR.
The laser is collimated but not focused so by your logic it will be fine.
This is advice on par with eating tide pods.
About all we can agree on, I think, is that neither of us knows enough about the product to argue about it usefully.
Unlike you I do know what I'm talking about.
