If someone knows better, please pipe up, I'm more than intrigued.

It takes practice to accurately judge how much indicated overexposure you can get away with before the data becomes irretrievable, but when you get it right it makes full use of the dynamic range of your camera's sensor. Of course, if you are photographing fairly static subjects you can hedge your bets by exposure bracketing.
That's true of the camera models with the latest sensors such as E-M5 onwards (as you have also indicated) but the earlier models with the 12MP Panasonic sensor (& also a camera such as the Stylus 1) does not have the luxury of having that extra headroom (or much of it) within the raw file & therefore extra care needs to be taken not to blow the highlights (where it matters) but at the same time not to expose to the left either to maximise the detail possible from the exposure. That's my opinion anyhow. I would agree with the AE bracketing, something I should use occasionally.
I fiddle with violins (when I'm not fiddling with a camera).
