Earlier quoted context omitted.
Large HIV database inflating matches is indeed a big concern. But dismissing one miss matches sounds arbitrary: these segments were not arbitrarily selected, but real insertions on tops of sars.
Again, take any random six letter amino acid sequence and chances are high that it matches to some HIV protein. I just did the experiment with my first name that is coincidentally 6 letters long, and lo and behold: a match to HIV env protein! Has my first name now been designed by a bioweapons facility?
No, of course not. Your parents were designed by a bioweapons facility, so that they would choose that name.
