The PPR is literally that - the passport request. If they already have his passport, no need to request it. As others have said, take ecas with a grain of salt, some VOs update it religiously, others couldn't be bothered. However, the PPR also includes a line where they request some brief info like height and eye colour, and also includes a request for photos for the visa. For applicants who are visa exempt, they could very well just issue COPR without any further communication, but since you're with the Jamaica office, I'm assuming he is not visa exempt? In which case, they would likely send you something just requesting those final details. It is a good sign that they kept the passport after the interview. Most officers know by the end of the interview whether they're going to approve you or not, so I doubt they'd keep the passport if they didn't feel they were likely to issue the PR. Good luck!
