Each instruction would constitute a CE and I would agree that you should record your understanding of the changes back to the Project Manager.
Contractually, I would argue that since any communication needs to be "in a form which can be read, copied and recorded" (Clause 13.1) then any further communication in the form of digital or hard copy drawings would be a change to the Works Information. You would, therefore, be entitled to a further CE (Clause 60.1(1)) should there be a difference between your intitial understanding and the final details once they are provided that results in a further change to time and/or cost.
