Seems right to me. But the'y' don't stop until next turn. They reform in the next manouvre phase.
I'm thinking they would reform the turn after they interpenetrate since reforming happens before any moves and they don't have any room to reform as yet. The farthest forward base will have to make one more move to allow room for the remaining bases to form on it.
I don't think so. They can reform in the next manouvre phase even if that's an enemy phase. The relevant rule is I think:
"It reforms into normal formation facing the direction previously faced by any of its bases (player's choice) and level with the furthest forward base in that direction. The final position and formation of the reformed battle group must be as close as possible to its position and formation prior to reforming. Bases in contact with the front edge of enemy bases must remain in contact with the same enemy bases."
So the reform has to be level with blue base A in your diagram, and as close as possible to to position and formation prior to reforming. Hence, I think what will happen here is that in the enemy manouvre phase the blue BG will reform such that it is 3 wide, 2 deep with base A being the left rear corner.
