Why doesn't SA1629 fire if the documentation ends with an XML closing tag?

For the SA1629 (DocumentationTextMustEndWithAPeriod) rule, I notice from the StyleCop source code that it will not fire if the text ends with an XML closing tag (i.e. last character is '>').

What is the rationale for this exclusion? I can't think of any cases where it would be appropriate.
