After rewatching the fight, Sasuke had bested Deidara from the beginning with his sharingan visual prowess and lightning specialty, making him superior to an Akatsuki member at the age of 15...
As we all know, the sharingan can see chakra in colors and minute movement of all sorts lets say 3 times faster than they actually happen. Meaning if the explosion lasted 2 seconds, Sasuke would be able to see it all go down in 6 seconds. Thats a Vine video right there my dudes. Thats more than enough time to summon Manda and glance at him (all this happens in 5 seconds sasuke time) and by the last second right before they reverse summon, the shockwave hits them which caused them to still take damage.
