How did Luke's proton torpedos enter the first Death Start after Red Leader's impacted on the surface?

I've always wondered how, after Red Leader's two proton torpedoes impact on the surface of the Death Star, were Luke's torpedoes able to even come close to making correct navigation through the thermal exhaust port? Wouldn't the explosion cause terrible damage to the surrounding area? Yet, we see no damage on during attack run prior, near, or after the target.

Canon or Legends is fine by me - I am just interested if anyone has unearthed more detail about this little chain reaction, so to speak.
