In other words, it should be in parallel.
Figures 1a and 1b.
What's important here is what nodes the components are connected to. It should be clear that in both (a) and (b) above that C2 is connected to A and B in both configurations and that C3 is too. The circuits are equivelant.
Because the ends of both components share common nodes they are deemed to be in parallel. The schematic on the right makes this more obvious and would generally be considered a better way to draw the circuit.
