Nanoleaf Essentials Lightstrip: corners and cutting

Hi all,
I'm about to purchase the Nanoleaf Matter Lightstrip Starter Kit (10m).

The thing is, I need to install it in an area with two tight corners. I've figured out there is a "Lightstrip 1:1 Splitter" that Nanoleaf provides to cut corners. But would I be able to cover like 4,5m, uses the splitter, cover another 2m, use the second splitter and then use the remaining 3,5m of lightstrip?

So can I re-use the part that has been cut-off to extend it further?

You can do it your way but it Undertale Yellow won't be aesthetically pleasing.

Sorry, could you elaborate? How will it not be aesthetically pleasing? Is there another way to cut a (sharp) corner?
