That is not the case, from the article that you criticized: > The first time it was used, the ultrafast camera broke new ground by capturing the temporal focusing of a single femtosecond laser pulse in real time (Fig. 2). This process was recorded in 25 frames taken at an interval of 400 femtoseconds and detailed the light pulse's shape, intensity, and angle of inclination. Obviously they're only recording extremely small timeframes with this setup, but it is indeed real time.
