They got that part right. It was one of the largest Mayan cities and appeared to be somewhat culturally diverse, with people from other Mesoamerican cultures living there as well, which is why it really isn't a surprise if that image does show a Toltec-style statue in Chichen Itza. It's about as surprising as finding a mosque in New York.
In grade school, the teachers didn't care about the content of our essays. They only cared about structure, grammar, spelling, etc. Which meant that most kids would restate the same thing fifteen times using slightly different words each time--not making a case by providing multiple arguments or pieces of evidence, just rehashing the same statement over and over. One of my teachers referred to it as "verbal diarrhea."
