The difference is explained under ":help :," which is also ":help :;" (a
few lines below ":help [range]")
If you separate the "from" and "to" parts of a range by a comma, any
search in the "to" part starts at the current cursor (i.e., at the same
place as a search in the "from" part). If you use a semicolon, a search
in the "to" part starts at the line defined by the "from" part.
