I was able to drag & drop from one document to the other.
In that case, you were working in Preview.app, not Pages. I reread your original post and realized that you were talking about PDFs. Oddly, the behavior of thumbnail Copy/Paste and Drag is opposite in Pages vs. Preview. Your question really has nothing to do with Pages.app, except that it was the source of your PDSs.
