Should the crew not have aborted take off as soon as the No.3 Engine TR ‘REV’ amber EICAS message displayed at
approximately 125.6kt i.e prior to V1?
We don't call stop above 100kts for a single amber caution as a general rule. At JNB stopping from around 130kts would have resulted in hot brakes and a nightstop. As the "rev" amber had no other symptoms such as vibration or thrust loss the decision to continue was correct. When the second "rev" came on they were above V1............
