»Is this important?«

Helo I am a new poster so bear with me please.
WHen Morpheues is giving his speach with the key maker and the other 2 captains he goes on saying"when i see 3 objectives, three captains, 3 ships i do not see coincidence, i see providence, I see (PURPOSE)" The crazy thing is that the word Purpose is spoken by AGENT SMITH.
Does anyone Know why?

If someone else has asked this i am sorry

One of the elements that the movies try to bring out is that the machines and the humans are all working in the same way. Morpheus says they have a destiny, the machines say they have a purpose. Both sides keep saying that they are being steered by some greater plan. Thus, somehow, they are all controlled by the matrix in some way, or by their genetic makeup, programming, soul etc.

In many ways, Morpheus is illustrated as a man blinded by the prophecy and thus very much a tool of the oracle and thus of the machines.

If anything is going to save humanity, it may well be the rusty catwalk of a poorly maintained human hovercraft.

The actual part I am talking about is specific. when morpheseus is saying his speach that one word is spoken by agent Smith as the scene shows the centinals moving towards a hovercraft.
My question is why the W. bros. would do that?
It is very specific one word.
