The grain goes in the same direction but the boards alternate - One board end grain concave next board end grain convex and so on.
I guess I don't know as much about wood grain as I thought (since I don't know what this means). My comment was partly from experience of planing an oak worktop made of small blocks laid up in no particular order.
