[GRASS-user] LIDAR tools and topology (unable to open ... on level

I find that after running each of the v.lidar.* the resulting vector
lacks topology, so I can't view the categories:
i.e. (after v.lidar.correct):
GRASS 6.4.2RC1 (ITM):~/GIS/DEM/LIDAR_EinYahav > v.category south_correct
ERROR: Unable to open vector map <south_correct at EinYahav_LIDAR> on level 2.
Try to rebuild vector topology by v.build.
So I run v.build, and then I get the vector with 4 different layers,
each with a different number of cat values (different max category).
Is this what is supposed to happen? Should I add a v.build step between
each of the v.lidar.* stages?
