Is it a good idea to iterate through several browsers in one test using Selenium WebDriver?

I am trying to run a simple test on multiple browsers, here is a mock up of the code I've got:

String url = "http://www.anyURL.com";
WebDriver[] drivers = { new FireFoxDriver(), new InternetExplorerDriver, 
                        newChromDriver() };

@Test
public void testTitle() {

     for (int i = 0; i < drivers.length; i++) {

         // navigate to the desired url 
         drivers[i].get(url);

         // assert that the page title starts with foo
         assertTrue(drivers[i].getTitle().startsWith("foo"));

         // close current browser session
         drivers[i].quit();

     }// end for

}// end test

For some reason this code is opening multiple browsers seemingly before the first iteration of loop is completed. What is actually happening here? and what is a good/better way to do this?

Please understand that I am by no means a professional programmer, and I am also brand new to using Selenium, so if what I am attempting is generally bad practice please let me know, but please don't be rude about it. I will respect your opinion much more if you are respectful in your answers.
