Depends, why do you believe you are seeing more often a particular word?
The reason defines whether it is apophenia or not. If you are delusional that it is an alien entity trying to communicate secret information to you in particular, by exposing you to a word more frequently, that's apophenia. If you know it is the frequency illusion and just find it kinda funny how it feels, then it isn't. Anyways, it is more often associated with the perception of patterns of causality in things that are random or banal. I'm of the opinion that this comic in particular is not a good representation of apophenia, other than the fact that the protagonist is certainly disconnected from reality.
