Pdf docs usually do have layers. They aren’t static images like. Jpg files.
Look up OCR- optical character recognition. Acrobat pulls out the text and adds it on a separate layer so it can be searchable. I’ll post more on it when im not on my phone.

A PDF of a scanned image starts with ONLY one layer- the image.
This one is made up of multiple layers

1) When opened in other pdf editors these layers do not appear. The pdf appears as one single image.
2)If the text were to be searchable text it would be consistent text in one electronic font and would not be a combination of dark and light (edited) characters as shown in the examples. This is more editing at the pixel level and NOT at the character level. There is editing on the signatures also and they would NOT be OCRed.
So I don't think the OCR layer theory holds up under this evidence.
