Seems reasonable. Of course there are really good (true) roundabout designs that are great of cycling (and walking), but without understanding the space it's hard to know if they would fit / work well.
What they're talking about is basically a small concrete circle (sometimes it's not a circle, but a round-ish shape vaguely near the center) plopped down in a standard residential intersection (sometimes with a lot of stuff in it that blocks the view in case you were worried about knowing if someone is crossing the street on the other side). Better designs likely wouldn't fit without raising the cost a huge amount.
