Well, G21 says
<G21> HOSTBOTS may DEPLOY MINIBOTS only onto their ALLIANCE‟S TOWERS and entirely below the DEPLOYMENT LINE. Violation: RED CARD. TOWER is disabled if MINIBOT is DEPLOYED above the DEPLOYMENT LINE.
G22 says
<G22> HOSTBOTS may not contact their ALLIANCE‟S MINIBOT while any part of it is above the DEPLOYMENT LINE.

Deployment line is defined as
DEPLOYMENT LINE – located on the POST, approximately 18 inches above the top surface of the BASE.

LOCATED ON THE POST there is no reference to a plane here or anywhere. It is a line on the post so my interpretation is that your hostbot cannot touch the minibot while it is on the tower post above the DEPLOYMENT LINE.

THe deployment line does not exist anywhere but on the tower post.
