Default Query regarding Noise Targets lecture 4

As per lecture 4 :- Slide 16/22

Noise target = Diterministic Target + Noise (This is clear)

However it then says :

Diterministic target f(x) = E(Y|X). Hence
y ( Noisy target) = E(Y|X) ( Diterministic target) + noise ( y-f(x) )

I do not understand the above statement. Did we not say that to accomodate for noisy targets we replace y = f(x) with a conditional distribution of y given x. Should then not the noisy target be defined by
E(Y|X) ?
