But it could also mean it probes TBs in all the plies except the last 6/8.

Meaning that if Nimzo is doing a X plies search, then the program probes the TBs
in the tree for all nodes that have a distance from the root below or equal to
X-6 (or X-8).

I don't think that probing the TBs in the first 6/8 plies of the search makes
any sense.
