My understanding is that new libressl code is under the openbsd license, though the original terms still apply as long as they have code under those terms left.
I was just pointing out that libressl is not under a different license from openssl < 3.0 as a whole, nor is it under the openbsd license as a whole. Rather parts of it are under the old openssl + ssleay dual license, and other parts are under the openbsd license. And over time, the fraction under the openbsd license is bound to increase, although as you say, they will probably never reach the point where all the old code has been replaced.
