I guess that if we're measuring bloodflow instead of neuron activity, then perhaps our knowledge of where in the brain something is happening might be off, but the results are not per se invalid. Things might only get tricky if more than one vessel feeds the same neuron.

Each blood vessel feeds hundreds of thousands of neurons.

That was not the point. Say you have a vessel A, and a vessel B, both feeding hundreds of thousands of neurons. Assume A and B both feed neuron X (one of those many neurons). Then A and/or B might fire up in a scan when X is active. The "and/or" is the tricky part.
