Not quite. None of the 5 hags currently released for 5th edition had immunity to saves vs magic. Night hags, unlike the other 4, does have advantage on saving throws vs magical effects, which Matt was correct about. However, Night hags are also immune to specifically the charmed condition, which would have prevented modify memory from working. So while it is possible it was homebrewed, to have the saving throw advantage but not the charmed condtion immunity, its also possible Matt just missed that part of the statblock.
