nit: Rephrase to:
Used for tracking consecutive reload requests.  If the last user-initiated
navigation (either browser-initiated or renderer-initiated with a user gesture)
was a reload, these hold the ReloadType and timestamp.  Otherwise these are
ReloadType::NONE and a null timestamp, respectively.

(Since they're closely related and can be covered by one comment, you can also
remove the blank line between them.)

Done.
