Both ends of the boot have ty-wraps. The hub side has a better grip than the blade side so plausible the boots remained with the hub. There is a repetitive inspection that requires removing the ty-wraps and pulling the boot back.
Also think the spar fractured somewhere in the middle to get this result. Anywhere else and only one blade would have left plus the gearbox.
