The Turnitin originality check system analyses the text and produces an originality report that lists all the text passages where the content of the work corresponds to the source material used for comparison. The listed similarities can be citations or references in accordance with good scientific practice, or they may point out inadequately marked citations in the text. The system sends the report to the supervisor of a thesis who assesses the quality and significance of the similarities. The supervisor can also send the report to the author of the thesis in order to give feedback and guidance. When the work has been analysed, it will be archived in the system database.
He gets the degree. Lets us assume the fellow did not published any thing further from that thesis and the thesis is not archived by Turnitin repository server. After 5 years if somebody copies a chapter from that thesis what will happen. If I am correct in understanding you, in this situation you have chosen not to add this paper to the Turnitin repository, therefore there will be no way of tracking any possible content which is taken and used in another piece of work by another author or student. Therefore in order to protect the intellectual property of your work I would encourage you to add your work to Turnitin database.
You will receive your Master diploma immediately after your Thesis defence. Therefore the green light is an essential part of the graduation process.
