Kinda, but not quite. Keeping a light foot on the throttle (which extends to more advanced technicues such as DWL and DWB) minimizes power demand on the car. This is a good thing even if it means less use of battery power via IMA. The reason: power for the battery is ultimately derived from gasoline through regen (forced or during braking) which involves conversion losses as you go from mechanical to battery and back to the wheels. In other words, you have to pay to re-fill that battery if you drain it!

The main purpose of IMA is to provide supplemental power to a smaller, highly efficient gasoline engine than the standard Civic. Think of it as something to use when you absolutely need it, but don't go out of your way to get into the assist. Not only will your mileage be excellent but you will save wear and tear on the battery with fewer and less severe discharge/recharge cycles.
