The flow of your code should be around because the first letter of the variable abc is a , which means that the second loop, search in each letter of the variable string the word a which is number 4 and will print it first.

Putting it always, if you invest the for, it will work perfect:

function ordenar(string){
  var abc = 'abcdefghijklmnopqrstuvwxyz',
      to = abc.split(''),
      str = string.split('');
      
    for(let j=0; j<str.length; j++)
    {
      for(let i=0; i< to.length; i++)
      { 
           if(str[j] == to[i]) 
           {
              console.log(to[i]);
              break;// detenemos el for
            }
         }
      }
}

ordenar('hola');
