The accessibility tree doesn't represent form elements in relation to their particular <form>, a submit button's position in the accessibility tree will be equivalent to its position in the DOM tree. The button's name (optionally also its description) and to some degree its position in the DOM order (what heading and/or other form elements precedes it) needs to be sufficient to convey what will happen when it's used.
