Is "Supervisor" the same as "Reports to"?

Hi once again.

Ok, easy one: I´m working in Process Author (see left side of picture) and want to set the criteria to 50m AND that "reports to" (field from the user profile) is a certain person.  Now, the field "reports to" isn´t in the drop down box. Only "current user," "supervisor," and "record owner." So, is "supervisor" in fact the same person as "reports to"?

And another one related: Is "record owner" the one who created the record?

I´m assuming that since there is a choice for "current user" in Process Author...

Thanks

P.s. my screen "handwriting" sucks...
