Quote:Does the jpg format maintain the two layers?

No it doesn't. It only includes the lower layer and ignores the higher layer. Layers are only added to eventually become part of a finished image. You need to merge them down before exporting to JPG. They are part of the process not an end in themselves. If you want to keep them export to XCF.
