Memory. Stiles was still there but already forgotten before being physically removed from reality.

Same with the kids room. Pictures still existed until he was physically removed.

It's the memories that have been altered. In the direct case of the person forgotten, this impacts the world by covering up all traces of them but the real trick, stated over and over again, is that they aren't remembered. That is a function of memory.
