Official Q&A: VRC 2019-2020: Tower Takeover

Hello, I know that the purple cubes along the autonomous line are neutral and can be picked up by either sides robot, but what if the purple cube is pushed passed the autonomous line into the opposing alliances side, but no other cubes are robots go past the autonomous line. Is that a DQ for the team that pushed the purple cube over or is that purple cube just considered neutral and if so how far can that purple cube go until its not neutral? Like if they pick it up and it rolls out of there robot and rolls to the wall of the opposing side is it still neutral or is that a DQ? Thanks for your time!
