According to the writers, it's because he smelled the cologne of two Tony Starks

I just rewatched the scene where he is on trial and had the subtitles on, yes u r right. Thank u!

Yea he says that to either Ravonna or Mobius.

I overall liked the Loki show, but the writers have no earthly idea what Loki’s character is. Combine that with stupid scenes like “I can smell the cologne of two Tony Starks” and it makes me have a stroke.
