Yes: We would copy the Note, and use that new copy in the Text Box block.
No: We would let the Text Box block continue using the same Note
But I think a better solution to this problem is implementing the ability to make a text box *not* be shared as a note in the first place. See https://bugs.launchpad.net/mahara/+bug/1152441
On the other hand, even if we implement that, we'll still have all the existing legacy Note blocks to deal with. So this still may be worth doing.
