you dont seem to have the comprehension to understand what was typed. it's like somebody saying: "he sailed on a boat when it was light until it was dark" and then complaining that it didnt count because it wasnt dark when he started
you cant. nobody said that. it's possible to be a non-league club before the Premier League existed and then get into the Premier League after it's existence. That is exactly the scenario in the original statement.
"top scorer" would mean any league I'm sure somebody would come along and say you can only rise from non-league to Premier League if the Premier League is in existence when you are in non-league.
"Tony Adams went from a youth team player to playing in the Premier League." Somebody who doesnt understand logic: "No he didnt. The Premier League wasnt in existence when Tony Adams was a youth team player."
