Array using is_tree custom condition is only working on parents

Hello. First of all, I have no idea how long this has not been working properly. It was just brought to my attention by my client, though, and I know it was working at one time… Perhaps over a year ago.

I’m assuming something changed in the processing of the array logic statements, but I can’t figure it out.

THESE WORK ON PARENT AND CHILDREN OF PAGE #32702:
is_tree('32702') and !is_tree('32702')

THESE WORK ON THE PARENT but not the children of the page IDs given:
!is_tree( array(32702, 36412, 516)) and is_tree( array(32702, 36412, 516))

If you need, here’s the function for ‘is_tree’:

function is_tree($pid) {      // $pid = The ID of the page we're looking for pages underneath
	global $post;         // load details about this page
	if(is_page()&&($post->post_parent==$pid||is_page($pid))) 
               return true;   // we're at the page or at a sub page
	else 
               return false;  // we're elsewhere
};

Any help from the author or community would be greatly appreciated!
