Mark Scheme for P3

I am bit confused on mark scheme of P3.
I am using kaplan kit. It states in mark scheme that every valid point is of 2 marks. I can see in the answer there are relatively longer paragraphs ( unlike other discursive papers eg P7) which contain a couple of smaller points.
Would each paragraph be for 2 marks or each point in the paragraph be for 2 marks?

If latter is correct, then each paragraph should contain more than 2 marks( like 3 or 4), shouldn’t it?
