// The result of the expression (true && false) is assigned to $g
// Acts like: ($g = (true && false))
$g = true && false;

// The constant true is assigned to $h and then false is ignored
// Acts like: (($h = true) and false)
$h = true and false;

I thought it was strange that Fuel used AND instead of && for this reason.

They are not the same, you should use whichever is correct for the task.
