Concession fares, at least on InterCity services are NOT available available off peak on weekends, they are charged the peak fare.
Direct from the online ticketing section of the V/Line Website:
Off Peak Concession/Child tickets are not valid for travel on weekends, so Peak Concession/Child fares apply for the return journey.

MYKI - concession can get a off-peak fares on the weekend
V/Line paper ticket - concession cant get a off-peak fare on the weekend
MYki - page 43 of the ticket book
Fares for all journeys in 3 or more zones receive an off-peak discount, except where touch off occurs
within Zone 1 before 9am on a business day or touch on occurs within Zone 1 between 4pm and
6pm on a business day.
Customers must touch on and touch off to receive the applicable off-peak discount. The discount for
off-peak travel is 30 per cent (this is applied after any concession discount). Customers who do not
touch on and off correctly will be charged a default fare that is a peak fare.
For customers travelling off-peak, the equivalent peak fare contributes toward the Daily cap, even
though a reduced fare is paid. For example when a full fare customer travels three zones off-peak,
100 per cent of the standard fare will be counted towards the Daily cap even though only 70 per cent
of the standard fare has been paid.
