Using switch emulators on the switch actually gives better performance?

[Plazorn]

In this Taki Udon video, a mig switch dumper is connected to a switch running linux, a Minecraft cartridge is put in, and the game emulated on what looks like Yuzu. This actually seems to yield better performance than that of the stock switch; in a comparison, Minecraft on the emulator barely had any issues loading chunks, which the stock is did. He just tested one game however, so I am not sure that something like breath of the wild would run better, but still, it is kind of funny in a paradoxical way.
