I do not think that Airbus are talking about engine failure when they talk about being "go minded" above 100kts.
Definitely not! Being Go minded is not a blanket clearance to just carry on. FCTM specifically mentions five categories of failures which call for reject takeoff even after 100kts. The second category is sudden loss of thrust also in the fifth category it gives five failures for which to reject the second is engine failure. To be go minded the aircraft must be controllable. A320 VMCG is 109kts and beyond.
