Revive a dead partner without an item

From Glitches

From the game Sword of Mana for the Game Boy Advance

If your partner is dead, and you only can save at a Silver Goddess statue, save. Then, turn off your GBA, turn it back on, and your partner will have 1 health; then you can use magic to heal them instead of wasting an item to revive them.
