In sci-fi shows which involve the main characters travelling back into their own pasts, protagonists are often warned that touching their past selves will cause a paradox (for example, in the Doctor Who episode 'Father's Day'). If you accept that being part of your own timeline is possible without causing a paradox, why does the act of two versions of yourself from two different times touching cause one?
