That unit will survive fatal hit with 1 HP left, it will be knocked back slightly further than usual too.

What is the usefullness? Againts enemies with long distance attack but slow rate such as Nyandam, Sunfish, Kory, Cathood or the likes, this ability allows for "retreat" move for those big units suppose if your meatshield defense is starting to be pushed back. For meatshields vs enemy which could take out anything in a single hit, this means increased effective meatshielding a lot

Example with imaginary stats:
 * Wall cat costs 150, taken out in 2 hits from X enemy, takes a total of 6 seconds to spawn two of them (3 seconds each x 2)
 * Pogo cat TF costs 240 at same time, taken out in 3 hits + 1 lethal strike = 4 hits to be killed by this same X enemy, takes only 4 seconds to spawn one of them but also only takes a single spawn slot in battlefield (remember you have units limit in battle)
