is that always so that the "which clause(non-restricitive) always come in between 2 comas"

it can be used anywhere
It's basically a one-way rule. If you are going to connect two independent clauses using "and" then you actually need "comma and."
But there are other circumstances in which you could have "comma and." For example:
She bought milk, bread, and cheese at the store. (list of three things)
She bought milk at the store, which just re-opened yesterday after a fire, and played tennis at the club. (the stuff after the "and" is not an independent clause, but the comma is necessary because it is enclosing the "which" modifying clause)
