As Pempu pointed out, the bottom left is a seki position.
As you’ve noticed, it can also be played as a cycle. However, this is not the typical type of cycle.
Under Japanese rules, black loses a point (since white captures two while black only gets one) every time he forces the cycle to occur and also gives white a free move elsewhere.
If black were to insist on playing this cycle endlessly (even with white passing on his free move at the end of the game), I don’t think it would be considered the same as playing a triple ko cycle endlessly, and shouldn’t result in an annulled game, since the points are just pilling up in white’s favor in each repitition and will more than compensate white for eventually just giving it up.
