I think I see where the confusion is coming from. Yes, the signal at the grid of V4 comes from both V1 and V2, but the signal at V3 also comes from both V1 and V2, not just V1. This is because the signal on the grid following the 'LTP' is derived from the difference between the two plates. Hence, differential amplifier. So, the signals at both grids go through one gain stage. Because each grid signal is taken from the different plates, they have to be 180 degrees out of phase (barring distortion of course).
