Hedgehog / Pincushion - Name changed

[0ptimistPrime (the Gray)]

Just a curiosity, since I thought it odd...
If you look at the Wild West webpage, they list the achievement as Pincushion.
In the actual achievements for PD2, it's called Hedgehog.

I wonder why they changed it. Was it a miscommunication between departments in the company? Do you think they changed it because TF2 has a similar achievement that went by the same name?

TF2:
"Pincushion -
Hit an enemy with 3 arrows, without killing them."

PD2:
"Hedgehog -
Get 10 or more arrows stuck in a Bulldozer at the same time."
