Yes, there is an apple 
in SF which is different from the Apple 
in NY
They are different.
The true non-dualist explores the reality of these apples. The reality of manifestation. The non-dualist does not stop at: yes, there are two different apples.
They go further.
The question that is posed in non-duality is, ‘What is the changeless aspect in our phenomenal experience?’
There are two different experiences called Apple A and B. Do they belong to the same reality or to two different realities?
For many people, this question is not relevant and makes no sense.
But for those who are interested in the nondual understanding, that question is central.
