Can a context that does not implement a separate XOF struct absorb and squeeze at the same time?

Some contexts implement separate XOF structs and provide IntoXof to convert to XOF structs, while others implement both Hasher and Xof traits directly. can the latter absorb and squeeze at the same time? Does the Keccak structure theoretically allow this?

Also, you can obviously clone a hasher state whenever it'd be safe to rehash exactly the same data, and then have those two hashers diverge.
