Could be that... or it could be where you are hitting the throttle coming out of a corner. If at full lean you are steady and stay steady till you are semi upright, then you roll into the throttle... it could be 'cleaning up' that section of tire due to acceleration.
Check and see if it is worn more or less than the rest of the tire.
From the wear evident I'd say you're overcautious in transitions both in corner entrances and exits. On the track the minimally worn section on your tire is the most heavily loaded from "backing into" and drifting out of corners. On the street that area is the one that will get you into trouble -- sliding in that region is the most prone to breakaway from contamination on the road (and it doesn't have to be more than a single leaf!) and an unrecoverable slideout unless you are a very experienced rider. Worse, if you are able to keep it on both wheels it's likely to highside.
FYI, that area is normally the fastest wearing on my tires, front and rear.
For everyone's information the harder the tire is pushed, whether by acceleration or cornering, the more the rubber looks shredded -- smooth means minimal loading.
IMO you're doing fine for the street.
If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

It's obvious - the outside, balled up rubber is where you put the bike on a stand and heated the tyre up with a paint stripping gun, thus melting the rubber on the outside edge to make it look like you cornered hard.
