This is a very loosing position for Black .I am not evaluating it from a Computer perspective .In this position Be7 is a better move though it looses the Queen because Kd8 allows Rd1+ check . Now it was only Queen & Knight who were attacking the King and after Kd8 Rook joins the attack .
The Black King has only two valid squares . Kc7 & Kc8 . The Black King is left wide open and the Queen, two Rooks and Bishop cannot come in between to intercept the attack . True after Rd1+ the Queen can intercept in between but anyways it is getting killed either by Knight or the Rook .On Kc8 White can take the g4 pawn and the rook on h3 will fall .
Be7 only provides an escape square for the King on f8 and King is not subjected to plenty of checks .
So the Queen and Rook falls leaving White with Knight/Rook and the Queen and with an unstoppable attack .A GM at this position would throw in the Towel if he/she were at Black's position.
