The and operator always checks both conditions, while the andalso operator does not always evaluate the second condition.

This statement is true.
The and operator will check both conditions - so if you write Brad Pitt AND Angelina Jolie, it means that the browser will check for both of those conditions. On the other hand, the andalso operator does not necessarily evaluate the second condition, so if you wrote the same think (using andalso operator), the browser may focus only on the first condition, which is Brad Pitt in this case.
