why is remake working only if the creature didnt reconnect at all?

i had vayne in my team ,i was jax jungle ,he bough doran blade and a pot ,came to red ,and like 5-10s before spawning of red he left ,wasting another 30 minutes in 4v5.

its really dumb he didnt even try to reconnect to game ,atleast once.

all game 4v5

then enemy be like GG EZ............

/remake should work if he gone. still lvl 1 still same items. still 4v5

i hate vayne in general btw.
