Maybe the situation can be explained easier. What is important - and when thinking about it, should wonder more people - is the question why light is actually bending at the two splits in the classical experiment. Because this makes the result clearer. The reason why a laser beam can behave like a ray until it hits the split and afterwards like a wave, is the Heisenberg uncertainty principle. The moment you define the location with high precision, the more you mess up the impulse. Thus, with the light passing a very tiny (certain) split, you create an impulse pretty random (uncertain). That is why suddenly the light can change the direction and move to the "side" instead of continuing its former trajectory. It is then when it can interact with another wave (even with its own) and get "diverted" (simplified speaking). With the temporal splits, it is the same. The shorter the impulse of the photon is, the more specific its location is defined. However, that gives a more random impulse. This is already well documented for single impulses. A "pure" red light (or laser of a single wavelength) in super short impulses (e.g. photons of synchrotron emitters) is located at a certain location and thus changes colors - since a different (uncertain) impulse means an uncertain energy. Another energy in light means another color. So if your light pulse is just short enough, it may change from red to green or so. This is not new, but might help understanding the next step. Like with the two waves in the spatial experiment, the two waves in short temporal distance can interfere with each other. This interferance is the pattern we see. Maybe that helps a bit.
