What does it mean to be 'self-hosting' here? Does it just mean that it's a compiler that can compile itself?

I believe so. FTA:

"Looking at my code, even though I wrote it, it feels magical to me that it can handle itself as an input and translate it to assembly."

yes

"Day 40 Hooray! My compiler is now able to self-compile everything!"

Thanks for asking the question I was embarrassed to ask - now I'm even more impressed with his accomplishment!
