I think it does in this regard: There is no prediction of damage to the attacking unit (or to be strictly correct, the damage is always estimated as zero). All other combat allows a realistic estimation of the outcome before committing the unit to the attack, which includes the damage to the attacking unit. All other ranged attacks (i.e. land and naval) would expect zero damage to the attacker - I think they just forgot to update the display for air units.
I appreciate that interception damage by fighters, SAMs etc. is a totally different issue.
