onsubmit return function

Question

isn't `return` redundant in onsubmit="return validate()"?

Full code:
<form onsubmit="return validate()" method="post">
Number: <input type="text" name="num1" id="num1" />
<br />
Repeat: <input type="text" name="num2" id="num2" />
<br />
<input type="submit" value="Submit" />
</form>

function validate() {
var n1 = document.getElementById("num1");
var n2 = document.getElementById("num2");
if(n1.value != "" && n2.value != "") {
if(n1.value == n2.value) {
return true;
}
}
alert("The values should be equal and not blank");
return false;
}
