I’m seeing more and more posts here where a single patterns is split into two parts and sold seperately. Is that allowed now?

You took the words right out of my mouth.
I've also seen patterns you can't buy individually. They're sold as a trio, for example, but each one is listed here.

I assumed it was allowed now.
