The truth of the matter is that it doesn't really matter if the current "hits" the capacitor before the pin of the IC or not. This has long been debated and recent studies have suggested that simply having the capacitor placed close to the IC is sufficient. Dave Jones of the EEVBlog did a video to help illustrate this, but he is most certainly not the sameonly one. I believe Rick Hartley, one of the world's leading experts in high-speed board design, has also proven that it does not really matter the order in which the current "hits" the pins. In most cases, it is actually preferred to have the capacitor connected to the IC pin through a plane, as that is lower inductance than a discrete trace.
