I do not recall seeing that in Berlin. But there also were not so many bikes that it really impeded the autos to have to yield to the relatively few bikes.
I did see that in Copenhagen, however, at certain larger or more suburban intersections, like this one at Bellahøj
IMHO, we're a lot closer in bike situation to Berlin than Copenhagen at the moment. It would be a glorious problem to have to have so many bikes that cars couldn't make a right turn -- and then, perhaps we'd need dedicated signals.
I didn't like being to the right of right-turning cars at first, but in six months of riding every day in CPH, I saw a "right-hook" once, and it was low-speed, and everyone walked away with not even really a scrape. I think three things really help, in that regard:
1. No right turn on red from the street with the cycle track
2. Stop lines adjusted so a bicycle stops well ahead of a car at a red light
3. Continuing the bike lane markings across the intersection, so it's very clear where the car is crossing the bicycle's right of way. (I noticed they've experimented with this on Port/Park, in the tight three-lane areas.)
