That’s a very understandable mistake.
What is not is publishing a copy of the BC with 9 distinct layers along with signatures perfectly aligned exactly 1 pixel above the line. That precision is not possible.
He may have a BC, but they posted a fake built up in Photoshop.
That's another birther fairy tale.
The layers are a product of the scan-to-PDF software they used. I am in the habit of using scan-to-PDF apps to digitize and OCR important paper mail before I shred it. So, I know how the software behaves. Often, when I open a scan, the document image will appear a fraction of a second before the text layer is painted onto it.
The scanner output is a series of raw, flat page images. During the conversion to PDF, the software identifies and separates out the text and OCRs it. The it packs the components together in the PDF, such that you can open the PDF in a viewer, search for specific words, and have them shown to you highlighted. It works well on a clean, laser-printed document, such as a bank statement. Not so well on the likes of Zero's long form, which contains a mix of hand-typed, haphazardly aligned text and hand writing.
