Both are not effective against Patriot missiles.
If the A-50 has EW jamming capability, it is obviously not effective against Patriots.
There are 2 explosions on the video.
The first explosion is at 54 seconds and the second (bigger) explosion is at 1+03. This indicates 2 missiles were fired at the A-50.
The A-50 probably had on-board or off-board notification of the Patriot launch, but was unable to defeat one of the missiles.
