I'm unclear on which example you mean, and I'm fairly certain some people just aren't getting how this works (despite several efforts to explain). Given access to enough special weapon abilities, stacking isn't really a hinderance to a smart archer (although, yes, he often does have to make choices instead of relying on the simple enhancement bonuses).
Let's see if we can lay it out for those who don't quite get it yet.
A weapon is limited to a total of +10 enhancements (non epic). Of these only +5 can be a true enhancement bonus (that is the +x to hit and +x to damage).
A bow can have +10 worth of enhancements (again at most +5 of true enhancement bonus).
An arrow can likewise have +10 in enhancments (again at most +5 of true enhancement bonus).
A bow grants all of its enhancements to the arrows it fires.
The enhancement bonuses (true) of ammunition and bows do not stack.
So a +5 bow with 3 different properties (that total to no more than +5 in bonuses) firing an arrow (with +10 worth of enhancements) will have its effects layered. That is the non-similar ones stack.
Now a weapon msut have at least a +1 enhancement bonuse in order to gain any other enhancements.
Therefor a +5 bow (with +5 worth of enhancements) will fire a +5 arrow (with +5 worth of enhancements) to yield an arrow with a +5 enahncement (+5 to hit/+5 to damage) and the non-similar +10 worth of enhancements.
Or a +5 bow (with +5 worth of enhancements) can fire a +1 arrow (with +9 worth of enhancements) which yields a fired arrow with a +5 enhancement (+5 to hit/+5 to damage) and +14 worth of non-similar enhancements.
Now composite bows also have a Str rating which applies to damage (and is not considered an enhancement) - melee weapons do not have anything similar to this that can apply.
An archer can fire a number of arrows based on his BAB and at range so that a melee combatant won't reach him until suffering through several rounds worth of attacks.
Now if the enhancement bonus of ammunition and bows was allowed to stack an archer could fire an arrow that has a +10 (+5 from bow and +5 from arrow) to hit and to damage and then he could add the damage from the str rating of a composite bow and he could affect targets at range (safe from melee attacks) as a full attack.
+10 to hit and damage is +5 more than a melee fighter can get with his weapon without adding in the str rating or the relative safety of the attack, etc.
Basically the fact that ammunition and bow no longer stack their enhancement bonus (for to hit and damage) is a reflection of how powerful the archer build was in 3.0. Almost no one is stating that the archer is not powerful as is (in 3.5) and yet some are arguing that they should be made even more powerful by allowing the enhancement bonus (to hit and damage) to stack (like they did in earlier editions).
