Can a married person claim Head of Household filing status?

I found the following post and confused by bullet 3. ..... (non-child dependents in your home don't qualify)
But someone's parent(s) or relatives can be the qualifying dependent(s). Your parents do not have to live with you to qualify.  I don't know about relative.  Even though some online posts state "direct relatives do not have to live with you. 
Can someone clarify bullet 3 - is it incorrect?
Thank you.

Even if you were legally married as of December 31, you're considered unmarried (and therefore eligible for Head of Household) if all five of these conditions apply:

  1. You won't be filing jointly with your spouse
  2. Your spouse didn't live in your home after June (temporary absences due to illness, school, vacation, business, or military service don't count)
  3. Your home was your child's, stepchild's, or foster child's main home for more than half the year (non-child dependents in your home don't qualify)
