I zoomed in here[link text][1]. [here][1]. The three boundary ways shown are all admin_level=4 which according to [this table][2] is the boundary of an entity (I confess I don't know what these are), which is the same admin_level used by the United States to mark states, so should be the same.
Where I have zoomed in, one of the three lines appears darker. I suspect this is because [it is a member][3] of two boundary relations, and the [other][4] [two][5] aren't in any. This probably also means the [boundary][6] [relations][7] aren't closed as they just end at this point.
Oh, in addition, at zoom 8 [the tile][8] hasn't been re-rendered since 4th September, so your changes won't yet be visible.
