Let me explain why it might not be.

If there is a train at a platform with 10 carriages. Assuming all people arrive on time, do they all get into the first carriage they see - no. They evenly disperse throughout all carriages.

Likewise, if you go to a park and there are 15 cafes by the lakeside, all beside each other. Do all the people in the park, looking for a coffee visit the first cafe - the answer is probably no. Again they seem to evenly choose.

Do you think the same happens in Google to a certain extent?
