Question related to mission What Is Wrong With This Family?

 

Hi!

I faced with trouble while testing my solution. So, i stucked in Extra chapter test 5/5. Task is ([["Logan","Mike"],["Alexander","Jack"],["Jack","Logan"]]). If I understand the task right the result should be "False", because there no relatives between Logan and Alexander or between Mike and Alexander. But as the result of test it display "True".
