Code Execution after successful validation for standalone forms and actions

for a standalone form, will all code after

$this->form->getState()

$this->form->getState()

$this->form->getState()

$this->form->getState() only be executed after all validations are passed?

And is the same true for the standalone actions? Will the

action()

action()

action()

action() method only be triggered after all the validations of the form are passed?
