Did you get the date in writing?
After seeing all these posts on LAing, I would make sure I got something in writing, signed by both parties. If the LA-er doesn't provide a standard contract (ask before you go), I would write out something at home and bring it with you with the following info.

It is understood that the Long Armer will contact the quilter with any issues.
The quilt top will not be altered in any way without written consent of the quilter.
Then the LA & Quilter will both sign.
Probably not a legal document, but it will go a long way to prevent misunderstanding
