You can have pH 7.2 water that has 0 kH

I guess you could. In a normally running aquarium kh
would be replenished with water changes and alkalinity used would not be enough to affect fish. If someone was running an aquarium on 0dkh then I'm sure ph would start to fall pretty rapidly.
In a fishless cycle I don't think ph of 7.2 would hold very long without a buffer.
If your tap is 7.2 and your dkh
was 0 then that is what the water has settled at with its chemical makeup. Since there is no extra acids added to the fray then it can hold pretty stable.
This is how I understand it anyway I could be wrong.
