The braces are used when there are multiple commands you want to execute after || but you could also write this as an "if then else" if that's more convenient. Then it's easier to add commands, too.
The braces and the semicolons are not necessary here, because everything up to "fi" (or "else") is executed when the condition matches. The || { stuff; } syntax is just basically a shorthand for when you want to cram stuff into a one-liner.
