USqlStreamReader.Split(delimiter) doesn't seem to work correctly

var stream = new FileStream(@"....\ExtractorsUnitTests\InputFiles\Test.json", FileMode.Open);
Encoding encoding = Encoding.UTF8;
var streamList = new USqlStreamReader(stream).Split(encoding.GetBytes("\r\n")).ToList();

Although, the file has multiple lines the "streamList" only gets the first line(first stream) as the output.
I also checked that it's not reading the entire file at once.

Any solution for the same ?
