I call bullshit on that one since the Ariane 5 is designed with a low thrust hydrogen engine as her core. My Ariane 5 uses a single frontier at the core and titans as SRBs on the sides. Basically the boosters are used as sustainers just like the real Ariane rocket, and drop off when the core stage have burnt enough fuel to reach a sustainable TWR. Then it will continue her way into space.
