Yes this could work. NTFS has a lot of information about when files has been accessed and modified. A simple check of these values would speed up the process. Would only need to copy the needed files if dates or other flags match, without rescanning hashes.
Not sure if it works this way, but there is a slight possibility it could. So for now it's still pure speculation.
For me, updating to 15031, the high CPU usage during initialization suggests the files were hash checked on multiple threads to speed up things. I had ~60% HDD usage and about 60-80% CPU usage. Earlier HDD usage was 1-5% and CPU usage was 25-40% during this phase.
