Found a detail: seems only to happen when 'visual keying' is on in user prefs.

That’s expected behavior, 'visual keyframing' sets keyframes of object in world space, not in his local space (such that you can later remove parent relationship, and still get object transformed as if it was parented e.g.).

If you want to keep parent transformation, then use usual keyframing.
