Dispenser And Stair Quirk

[faiyde sp04]

Messing around the other day and found that when a dispenser fires an arrow directly into a stair the arrow can be picked up from about 15 blocks away. This happens singleplayer and on massive.
it doesn't seem to happen when the stair is a solid block, or when there is a space between stair and dispenser.

Can anyone explain to me what makes this happen?

and pixies isn't a valid answer

-shrug- Minecraftia it seems, has a fair bit o' magic about it.

(ooc) A bug. Report it on Mojang, if you think it a pressing issue.
