Can this even be installed in M.2 Slot?

I've had asked a question a day ago about what kind of an SSD would be appropriate for my Aspire V Nitro VN7-791G laptop, the thread can be found here

and the SSD Drive I found appeared to be valid. I'm no expert and this might seem funny for tech gurus, but surfing another forum I've found the motherboard of my exact laptop and it looks like this

And here is the SSD I found online and considering to buy

And the thing is, zooming in the motherboard picture, you can see M.2 slots' connection port and it has only one split at one side. Sorry, I don't know how it's called technically. To clear myself up, I mean these (pointed at with yellow arrows)

My chosen SSD has two of them.
I have seen SSD's with one "split" too, so I'm frustated. Here's what I think it should be.

I don't know difference between both of them either. Can both types be installed? Or only with one split?

Thank you very much! I'll definitely ask you something if I'm required to.
