Shang-Chi Vital Balance not counting as separate hit


When I use Vital Balance, sometimes the tile destruction damage and subsequent matches seem to get bundled into a single hit of damage. Enemy grocket had triple digits health, I use VB and he is downed but the next enemy in a row took no damage from the matches VB caused.

The "sometimes" seems to be either of a match 5 occurs or the damage would also down the last enemy. I'm not sure.
