I hope that helps you out.

Yes and the alternate circuit has C3D negative lead going to B+ and the positive to B Boost, so it's still polarized correctly for that scenario. I suspect they did it that way so that full B boost voltage wasn't across C3D, because B Boost likely swings above 500v during warmup. Off hand I have no idea why they went to a non polarized cap unless it's exposed to negative going spikes on the B Boost. If by chance you used a 450v cap for C3D it could become unhappy with full B Boost across it.
