Common app: If each college asks for 2 letters, does that mean i need that many from diff people?

I’m applying to about 6 universities on the CA, and all of them require two letters of rec. Does this mean that they all have to come from different people, and all have to be different letters? I cant just have two teachers/advisors/etc send the same letter to each college? I would need 12 people?
I’m confused, I appreciate all help!

2 letters from 2 different people.

You can cover your entire pool of applications to colleges requiring two rec letters by having only two people and each sending the same letter to each college (unless, of course, they are adding anything that would refer to the particular college)

The same letter can be sued for every college application. You only need two letters.
