Usually the 75 is next to the output tetrode (or pentode) and so the grid wire picks up the output signal which creates positive feedback and oscillation. Leaving the grid wire inside the shield reduces that feedback.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
