Not sure whether a mounted goblin is dismounting then running when fleeing while mounted, or if the spider is supposed to flee with him, but either way the echoing is definitely wrong.

You narrow your eyes and glare in Noggard's direction.
Your fatigue MASSACRES Noggard!
Noggard has fled!
Noggard leaves south riding on a giant spider.

You parry a giant spider's chomp.
Your shield blocks a giant spider's chomp.
A giant spider dodges your cleave.
The minotaur mercenary screams and attacks a giant spider!
A giant spider is in perfect health.


I would expect either Noggard to dismount and then just see "Noggard has fled! Noggard leaves south." or that they flee while he's still mounted, and that when Noggard flees, the giant spider does also and flees the same direction.

Goblins now auto-dismount on flee.
