And then of course, add in the spice of the fact that people tend to remember things that validate their theory more than they remember the times it didn't pan out. This has kept the moon rumors alive for almost a DECADE despite there being no long-term, high-sample evidence for it whatsoever. Look up the rumor that the number 47 pops up more at random than any other number, or plug 666 in and watch what happens. These theories survive for eons.
They got an HQ on a moon? HOLY SWEET MOTHER OF DJIGGA IT WAS A MOON-HQ!

I'd say that's probably what's going on here, too.
Gimme 1,000 samples of minion kill and 1,000 samples of not minion kill and we'll work out the stats.
