This is one of the differences between ARIA properties and HTML properties such as hidden, required, disabled etc. You cannot explicitly set these HTML properties to false -- by simply including the attribute they equate to true. ARIA Boolean properties can expressly be set to true or false. I imagine this was done in ARIA to indicate instances where something clearly needed to be indicated but it might not be clear through native semantics without ARIA.
