Not trying to be a dick or anything but all weiss beer sold in States needs to be rolled in the same way. You had an unfiltered beer is all. Thats not exclusive to Germany. I'm shocked you've never had one elsewhere. Unfiltered beers are getting more and more common these days. I personally like them a lot. Once again I hope I'm not coming off as a beer snob or anything.A long time ago I was at a bar in Nuremberg. It was my first time in Germany and my first real experience with genuine German beer. Each bottle had floaties in it, too. The bartender went through a fairly complicated process of rolling each bottle in his hands and on the bar before serving us. I was told that this was the process for settling the yeast on the bottom of the bottle before pouring it into the glass.
So in answer to your question, yes, it is safe. Older, more traditional techniques for brewing do result in residual yeast and other ingredients remaining in the bottle.
I'm glad it all worked out for you.

You must be like my friends who don't venture far from American style pilsners and lagers. Which by the way are some of the best beers you can buy. Seriously Miller Lite is regarded as one of the best pilsners on the market in blind taste tests. Some beers snobs genuinely love it.
