Yeah, seems like there's a mistake since some people identify Suzaku/Zhu Que and Fenghuang as the same being while in the myths it is a different story entirely.

I think that the indication of Kurenai summoning the Fenghuang instead of Suzaku (or Zhu Que for that matter) can mean that he has acquired a different, yet similar family beast compared to the main Himejima line (or if the Slash/Dog line has any indication, Suzaku the person allowed him to do so).

The main similarity between Fenghuang, Suzaku and Phoenix is that they symbolizes fire and rebirth. Other than that, it depends on the culture. Here, I have a speculation that the Fenghuang Kurenai summoned is just a tier below the real Suzaku (If we go as far as the Oriental symbolism can allow).

Fun Fact: Fenghuang is traditionally associated with Females (and Dragon for the males) in Oriental weddings or royalty AFAIK, and it can be interpreted as a symbolic sign of how Akeno's relationship with Ise evolved in the future, aka. the Dragon & the Phoenix, husband & wife (however, this symbolism can apply to other girls as well, namely Ravel).
