Last chapter of John Mulaney's challenge - is it intended?

Desmo

All the previous chapters have teleports from each single lane to the boss, giving the option to take how many lanes you want and then take the boss. Which allows to go back in a second (or third, forth....) time to take the missing lanes and boss again.
The last chapter, which has ridiculously stacked opponents, does not give that option, meaning you have to go through all of them at once.
Was this intended or Kubam just forgot some teleports?
