I wonder if they adjusted it since reading this thread, or if you forgot to turn on reasoning or if you just got unlucky. For me, when I ask this it thinks for about 1.5 minutes and responds with

"The Brazilian citizen needs to clear immigration in Lisbon."

When I asked it to explain why, it said

"The Brazilian citizen needs to clear immigration in Lisbon because Lisbon is the first Schengen entry point when traveling from a non-Schengen country (Brazil) to a Schengen country (France via Portugal). According to Schengen rules, travelers must clear immigration at the first Schengen port of entry. Since Paris is also within the Schengen Area, no additional immigration checks are required upon arrival in Paris."
