well, no, they've got no meaning in the other one
basically it's something like that :

public class MyClass
{
	private string login;
	private int uid;
	private string home;

	public MyClass (string line)
	{
		System.text.RegularExpression.Regex.Split(line, ":");
		/* make some checks
		 * (second field is an int, and so on ...) */
		// call next constructor
	}

	public MyClass (string login, int uid, string home)
	{
		// affect things
	}
}
