You might be thinking of a different kind of indices :) These "indices" are essentially just the names of VBOs created by the OpenGL driver (like file handles). This example uses a vertex buffer, but not an index buffer, so there are no primitive indices that map primitives onto vertices in the buffer -- the glDrawArrays() call just assumes an index buffer of the form {0, 1, 2, 3, 4, 5, ... }.
