Why did Jotaro's Star Platinum's punch destroy DIO's The World?


Towards the end of episode 48 of Star Crusaders, Dio kicks at Jotaro who uses
Star Platinum to punch The World's shin. Star Platinum's fist ends up
cracking, but then The World's entire body ends up cracking, killing DIO in
the process.

How could this simple punch kill The World?




Remember when Joseph and Avdol meet Jotaro in jail and told him that Stands
were a manifestation of life force? That's the same principle of hamon and
that's the reason DIO isn't immune to them.

And for completion sake i'll add a quote from the author itself:
