From M9-G8's page:

When using M9-G8, the source of the reroll is the ship equipped with M9-G8, not the ship attacking. For example, if a ship is attacking with Snap Shot, a ship equipped with M9-G8 can cause that ship to reroll a die.

Therefore prior rulings show that M9-G8 is the source of the reroll, therefore the attacking ship could still reroll another die.
