I read it the same way. I should've gotten way more RAM back when I got my M1 and RAM was still cheap although this was of course before the LLM boom so there was no way to really know.

I maxed my M1 out when I bought it because I was frustrated with the 16GB max in the previous machines. I use my machine for all sorts of things and some days you just don't feel like exiting apps to make space for new ones.

I still don't have a strong urge to upgrade. I could probably get by on 32GB (like my work-issued machine is) but 64GB is the right amount of headroom for me.
