I don't know what reference you are looking at, but the specification 
says:

Since the p element can contain only *phrasing* content, the hr element 
is not permitted inside (since it is allowed only where *flow* content 
is allowed).

The end tag for the p element is optional.

Since the hr element is not allowed inside the p element, the hr start 
tag also ends the p element.

The p end tag therefore doesn't have an open p element to close.
