This is usually called the metagame and evolves over time. My guess is that due to these unseen tactics the metagame will change and human playstyle will become more AI-like and adapt to the changing circumstances. The real question is whether people would be able to keep pace with rapidly changing AI playstyles?
Depends on if people can figure out how to evaluate the more random seeming 'AI style' moves. With the complexity of Go it's possible to only way to really tackle the complexity is to wrap groups of moves together in a local narrative.
