Engine braking in most petrol cars is an efficient tactic due to DFCO[0] - less efficient than coasting in neutral, but you're not as in control of the car when not in gear, so the combination of both being in control and getting a "free" slowing effect (especially when judging upcoming traffic, as opposed to coming to a complete halt) can be better than just mashing the middle pedal.

If you're slowing down to traffic light, it's more efficient than coasting in neutral. You've to slow down anyway and slowing down with engine braking is 0.0l/km. While coasting still burns some fuel.

In addition to that, some newer cars charge battery when engine braking. Which is effectively saving fuel later.
