TCA9617A: TCA9617 current leakage

Part Number:TCA9617A

Hi 

Customer see when Vcca is 3.3v and Vccb is 0v, because the scla sdaa have a external pull high.

But they found scla and sdaa are 0.9v, sclb, sdab and en pin are 0v.

I see datasheet say that

due to ESD protection requirements on the SCLA and SDAA, it is required to power-up VCCB prior to VCCA. IF SDA and SCL (on A-side or B-side) are pulled up to a positive voltage before VCCB is powered, there can be significant current leakage into the SCA and SCL pins that could cause them to be pulled down. The SDA and SCL lines shall not be pulled up to a voltage higher than VCCB, even when the device is powered down

so is it the same case?

thanks.
