why is xset a higher seed then ghost

they have the same group stage stats, but ghost has a better round diff, i dont get it

cry

head to head xset won

xset beat ghost

the tiebreaker is

1. head to head
2. map diff
3. round diff

XSET won against GHOST in h2h

Because xset beat ghost so because of that xset is the first seed and ghost 2nd
