Why won't this work on step 3 of the code challenge for multidimensional arrays?

In the third step it ask you to replace the hard coded output with the values in the array. I originally came up with this:

echo "<li>",implode(" : ",$contacts[0]),"</li>\n";
echo "<li>",implode(" : ",$contacts[1]),"</li>\n";
echo "<li>",implode(" : ",$contacts[2]),"</li>\n";
echo "<li>",implode(" : ",$contacts[3]),"</li>\n";

but could not complete the challenge until I did this:

echo "<li>".$contacts[0]['name'];echo " : ".$contacts[0]['email'];echo"</li>\n";
echo "<li>".$contacts[1]['name'];echo " : ".$contacts[1]['email'];echo"</li>\n";
echo "<li>".$contacts[2]['name'];echo " : ".$contacts[2]['email'];echo"</li>\n";
echo "<li>".$contacts[3]['name'];echo " : ".$contacts[3]['email'];echo"</li>\n";

Can anyone explain the difference between these two if there is any? They both looked the same in the output to me. Was this just treehouse being nit picky or is there a real difference between the two.

Thanks

Sorry for the delay, can you post the challenge this is referring too.
