Yes, this can indicate over-sharpening. I can't comment on the M8's in-camera sharpening because I shoot only RAW. And zero sharpening is my default both in Bridge at pre-conversion and in PS--post-coversion.
However, some files that are perfectly focused and with optimal lens use can benefit from light USM. I should note that these are not recommended protocols, but habit and a personal aesthetic (which I might, one day, call a style). What's not personal, and seems to be common practice, is to sharpen as a last step in one's post processing.
I'm inclined to toggle sharpening because without an A-B comparison, whatever I'm looking at normalizes in my vision and starts to look best. Because I sometimes prefer less color intensity than what the M8 produces, I will tweak down saturation--in which case I might sharpen a file I otherwise wouldn't.
