A snippet is a new song that references the same file as the original but with a different page order. Annotations are not stored in the PDF - they are stored in the MobileSheets database and are separate for each song. However, if you do want them to be embedded in the PDF, you can use the "Embed Annotations" option in the annotations editor to make that happen. Then the annotations would show up in every song that uses the same file.
