That's what I'm saying - if the scans have caught the large void (by being placed in the grand gallery) and the small void (by being placed likely in the entrance hallway leading to the gallery) then they are at the proper location to capture any pathways above them. But since no pathways were detected - then the theory is likely incorrect. But perhaps the location/shape of the void isn't as accurate as depicted.
