Tape over hoods was due to condition of the brake hoods. As mentioned this was likely their last rodeo and even after applying product to restore their surface the edges were cracked and rolling them up to tape under would have resulted in a tear or worse. So wrap over protects the frayed ends of the hood and avoided their destruction. These are likely the original hoods and that they are not turned to goo and can still provide a firm grip to your hand is wonder enough.
