No, That tool, as valuable as it is, doesn't tell you everything and doesn't even address the OP's issue. (Unless you adjust it to exactly equal lengths, right and left, then use it to clamp in a disk. Then you can sight down the disk. Does it line up with the seattube? The head tube? Do you do that? For that the properly dished wheel is easier.)
I love those H-tools (though it took until this thread to learn that name) they are of little help in locating the dropouts relative to the frame. Hubs (axles and bearings) love 'em.
