Validation.Errors is an array and you get the first element in that arrah/list by using "index" 0. To get a certain index in an array, you use [ ].

In this case you basicly say:

Give me the first record of the Validation.Errors

Validation.Errors Gets the collection of all active ValidationError objects on the bound element.

You could get all validation errors by using the enumerator like this:

foreach(var error in Validation.Errors){}

In case an Array is Empty, there wont be any elements at [0] thus throwing an IndexOutOfBoundException.
