Looks like a tensioner of some kind, but I'm really not sure why you'd need it? Seems like it's over-complicating things a bit.
 
Turns the cable 90 degrees without the attendant friction of the cable inside an outer (and increases the turn radius of the rest of the cable from the chainstay stop. [ETA: This reduces the pressure required with the right thumb on the shift lever; and image.]

Correct - https://bike.shimano.com/en-NZ/technologies/component/details/wheel-type-cable-guide.html and used on quite a few Tourney TZ rear mechs.

Odd that Shimano use this on their very low end MTB range, yet SRAM use it on their top end Eagles
