It's unsafe but the blockstun is relatively short, so especially online it can be hard to punish (akin to Nyo P+K and the like). It also has some good range on the hitbox/hurtbox, and will generally extend further than throw range, if a player wants to stay in that midrange.
Or you could just listen to an Ayane player tell you to use more tracking moves kek
