On the contrary! Check out the events here:

- Gilgamesh starts to run away.
- Shirou runs after him.
- Gilgamesh realises he can't escape and tries to pull out another Noble Phantasm.
- However, Shirou is faster and is about to slash him with Kanshou and Bakuya.
- UBW is washed away by the magical energy coming from the lake, but - importantly - "[t]he match is settled", Shirou can still beat Gilgamesh by "slashing with [the] twin swords". The only reason he doesn't is because the void immediately appears in Gilgamesh's stump to try and absorb him.
It's more than just the sequence of events, the tone of the scene was changed on a profound level. It goes from Gilgamesh being completely humiliated to Shirou falling on his knees while Gilgamesh regains his composure, praises Shirou in a dignified manner, and prepares to kill him, and is only stopped by the void appearing. In other words, it's a complete reversal of the original scene.
