wait what? using a whole linux kernel as firmware before booting another OS to improve speed, reliability, security? does this seem strange to anyone else?

Check Ron Minnich's talk explaining the why:

(The video of the presentation is linked in the OP).

There's already two and a half obscure OS's running underneath the OS for booting. So this replaces all that crap with something lean and good.

Similar philosophy to Petitboot, for which the rationale is given here: https://www.youtube.com/watch?v=CQueOHKO58M

Obviously it's a heavy weight solution, but the idea of having more drivers and better support is compelling— it's a much easier path to exotic boot setups, eg over wifi, off a SAN, whatever.

why boot linux then boot linux again, rather than just booting linux once?

UEFI is a heavy-weight solution in comparison as well. You can compile some pretty small Linux kernels.
