Released energy by fusion reaction

Video Link
According to the video in the link above the binding energy for deuterium is about 2 MeV and the binding energy for tritium is about 8 MeV so the total for the input items is 10 MeV the binding energy for helium is 28 MeV I am confused by this part if the resulting binding energy is higher that means the extra energy is being taken not generated Can you please explain how come 18 MeV is release , I thought it's needed not released.

Binding energy means the energy you need to add to separate the constituents or, equivalently, the energy you get out by assembling them. Therefore, you gain the binding energy when you assemble something.
