Trace fork for bypass capacitor OK? Why?
For the functioning of that IC, it's always best to have the high frequency decoupling capacitor as close to the pin as possible. It's less important whether the power supply trace comes in to the IC pin or the decoupling capacitor.
In some circumstances, we are concerned with the coupling of noise from that IC to other devices that share the power supply trace, and in those cases it is slightly preferable to have the decoupling capacitor on the power supply side of the IC. However, if we are concerned about such noise coupling, then we would likely be using additional means, like series resistors, ferrite beads or inductors in the power supply traces, in addition to decoupling capacitors. The effect of these will be orders of magnitude more significant than the order of IC and capacitor on the trace.
