I would not of thought that you abort a start based on 'no fuel' scenario...especially when there is starter limitations way above this limit which would permit you to continue motoring.
In any case I recently spoke with a good friend of mine who is a PWC Tech Rep and he stated the 10 second limit is for the exact opposite...if you have more than 10 seconds worth of fuel in the engine before light-off than expect a hot start. Another words the limitation is there to prevent hot starts.
Unfortunately I don't have any reference for this and would not recommend to test the theory!
