Let $A$ and $B$ be positive-definite matrices such that $A \le B.$

By matrix monotonicity of the root, this also implies that $A^{\alpha} \le B^{\alpha}$ for $\alpha \in [0,1].$

I am now curious under what assumptions we have 

$$ A^{\alpha} B A^{\alpha} \le B^{1+2\alpha}$$
in the sense of operators?
