From Borg's perspective, Lin Li was still too young, and couldn't look at things rationally even though he was already a Legendary powerhouse. Although he was confident that Cheyenne would agree to collaborate with him despite the fact that the Dark Blade and the Malfa Family had been in conflict for so many years, he was worried that the young Master Felic would still have ill feelings because of what had happened earlier.
All the Legendary masters here, including Cheyenne, knew about the conflict between Lin Li and Stephen back in the Blackstone Mountains. Hence, they guessed what Borg wanted to do when he called Stephen in. Lin Li also knew what Borg's intentions were. Such things had happened to him so many times since coming to Anril.
