uses tag not work

https://manual.phpdoc.org/HTMLSmartyConverter/PHP/phpDocumentor/tutorial_tags.uses.pkg.html
"The @uses tag automatically creates a virtual @usedby tag in the other documentation that links to the documentation containing the @uses tag. In other words, it is exactly like @see, except a return link is added automatically."

//classes.php
class A {
/**
* @uses B::b()
*/
function a(){}
}
class B {
function b(){}
}

$ php -l classes.php && phpdoc -f classes.php -t docs
No syntax errors detected in classes.php

I checked the page docs/classes/B.html#method_b and I see that there is no reference (@usedby) to A::a().
Why?

Start with the @uses example in classes.php and reproduce it with phpdoc -f classes.php -t docs. Inspect docs/classes/B.html#method_b for the missing @usedby reference and trace how phpDocumentor handles the link. Done means the generated documentation for B::b() references A::a() as described.
