Whether it returns a false or empty array for a non-existing path seems to depend on libxml version.
I tried the following code:
<?php
$data = '<foo><bar></bar></foo>';
$xml = simplexml_load_string($data);
print gettype($xml->xpath('/first/second'));
?>
On a machine with libxml 2.6.16 and PHP 5.2.8 I got back boolean. On a different machine with libxml
2.7.3 and PHP 5.2.8/5.2.9 I got back empty array.
You can check the libxml version from command line by executing: php --ri libxml
or simply look at phpinfo() output
