I wonder if that’s how the town got its name? [gee golly willickers face]
The town name derives from the name of the original Greek colony, Aspálathos or Spálathos. The Romans made that Spalatum, which in the Medieval dialect became Spalato. The South Slavs called it Split in their language.
The English word derives from a Medieval Dutch word, Splitten.
So, it's just coincidence, but one that makes for lots of double entendres and puns. :-))
