This would allow for some 469 2010 stuff that the GDC obviously doesn't want.
G41 does not prevent a 469-2010 strategy. Consider the following situation:

Red robot A, starting in the opponent courtyard, moves under the low bar and sits there. Robot A is fully outside of the neutral zone, and still contacting the carpet in the blue courtyard. A red HP rolls a boulder toward the low bar. This ball comes into contact with robot A inside of the outer works. Robot A then shoots the ball high.

G38 was not violated assuming the cycles are slow enough.
G39 was not violated since A was in contact with the carpet in the opponent opponent courtyard.
G40 was not violated since A did not cause the boulder to move from the neutral zone to the blue courtyard, but rather from the outer works to the blue courtyard.
G40-1 was not violated since the HP was transferring the ball to the outer works, not to the blue courtyard.
G41 was not violated since this was not a CROSSING considering that A came from the courtyard, not the neutral zone. Even if CROSSING were for some reason defined bi-directionally, A still did not cause any boulders to move from the neutral zone to the blue courtyard, but rather moved boulders from the outer works to the blue courtyard.
