Engine braking is when the engine is retarding the wheels when the clutch is engaged and the throttle is lifted, because there is less power developed than required by the wheel speed.
That transitional effect of the clutch engaging and having to spin the engine up to speed is called inertia braking. That will cause miniscule clutch wear, but might cause you to spin out when the clutch is let out too suddenly and you where close to the adhesion limit.
This is removed with re-matching downshifts.
