TCA39416: Application: Could Port B be connected to Controller?

Part Number: TCA39416

Tool/software:

There is a typical application in the datasheet of TCA39416. Port A is connected to Controller and Port B is connected to Device.

Here in my application, VCC of controller is 1.8V, VCC of device is 1.0V. Based on VCCA<= VCCB, so I have to connect Port B to the Controller, while Port A is connected to the slave device. 

The picture below shows my application. Can this work?
