It could also be that the battery is above optimal charge, at that point the motor generator will spin the ICE just to run down the battery a bit.
There's a lot of reasons why the ICE might be running when you think it "shouldn't" but that's because there are a lot of factors the PCM takes into account when it makes its decisions.

Simplying having the ICE running won't make a huge differance in your fuel economy, the engine consumes very little fuel at low RPMs and 5 minutes of idleing won;t make a big differance. Running at high RPMs even for a minute or two will however have a big impact on economy.
