Addendum: and keep in mind that the DR / SNR numbers are calculated based on optimum exposure (to the right), and not based on exposing to the camera's meter. If you expose to the camera's meter with the E-M5, you'll underexpose by about a stop, and the resulting DR will be lower than the maximum possible DR had you exposed optimally to the right.

Am I right that dynamic range will be lost in RAW post-processing when brightening?

No. The dynamic range of the image will not change in PP unless you clip the highlights when so doing. Pushing the shadows will, however, make shortcomings with regard to DR more visible.

If so, why did Olympus do that?

Olympus didn't do that. Their idea is to leave more headroom in OOC jpegs before the brightest highlights clip. For RAW shooters, the way Oly has calibrated the camera ISO doesn't matter as long as you know how to expose optimally.
