If neither of those then yea it seems kind of superfluous. But hey, at least it looks good!
It. Is. Energy. The projectile for a electromagnetic mass projector like this or the Gauss is insignificant to the electrical energy needed to drive it to the speeds needed. It has nothing in common with Guns as far as functions beyond "projectile flies down barrel". It has plenty in common with energy weapons in the electrically based nature of operation.
The skills represent more than "point and shoot", it is general operation of the weapon. E-weap users don't have to worry about feed jams or barrel heat, Guns users don't have to worry about smudging the emitter optics or making sure the plasma containment is optimized, or whether the accelerator coils are firing in sync.
