From what I understood (which wasn’t much, since either the original text or the translation is broken), the guy was there checking the department’s workflow and assignments. He found out most of it ends up with Tokimori and he is suggesting that Sugawa is assigned to help her with such workload.
Seems to me like the writer’s excuse to have them spend more time together at the office environment.
The guy hasn’t really been shown to be even remotely interested in Tokimori. If anything it seems he will end up being a wingman.
