Oh, that is the mechanic of area attack: units which enters the AoE after the attack animation started will not be hit. In return, units which in the AoE area during the attack animation will still be hit even when they knocked back by other units or base cannon to outside of the AoE. However, knocked back due to health point reduced to certain point is different since that knockback has invulnerability frames.

LD AoE however is the reverse: units which enter the AoE during attack animation will be hit, units which gets out of the AoE during the attack animation will not get hit.

If you wanted to test this, try hack evangelist cat and super quick recharge base cannon. Evangelist cat very long attack animation and its 100% stop to any units will make it easy to identify units which has been hit. Combined with quick recharge cannon, you can knockback enemies back into their base (if the map is short enough so the cannon wwve animation finish faster) and they got stopped at their base.
