I mean, that's pretty much ALL events...
Not really. Aside from a comic actually having to do with the event's story line, they just add the "tie-in" to a comic so it can be a part of what's going on in the story, but have no relation to the actual story line's progress.
Age of Ultron, Original Sin, AVX, the Ultimate Cataclysm stories and now AXIS are recent events that did this. For Infinity you had to cop the self-titled, Avengers and New Avengers to get the full picture of what's going on with the story.
