This is getting all too confusing. Need to go to starbucks and get my medium, oops sorry GRANDE, cop of black apron aged Sumatra to wake my ass up

It's still 2 spears, you just probably can't see it in the picture. I don't think you can extract the key with this setup without the 2 spears. that's why I say it's getting complicated.
Once they sold out of the first model, they ran around frantically trying to came up with an alternate solution. They can't afford to be out of stock on this with everyone buying jaspers and wanting to mod their box. But They ran out anyways as they didn't foresee the high volume of sales.
As if these setups were not confusing enough, and making everyone ask 100's of questions, they just made it worse in the name of continuing to make sales

I'll bet you $100.00 they will have another version that is better very soon. This model just buys them some time until they bring in something different or more of the very first version.
