TPS65266: please help check wehther the VIN can be powered after EN, thanks

Part Number: TPS65266

In our designing, we connect VIN1, VIN3,VINQ,EN1,EN2,EN3 together, but connect VIN2 to other circuit, which to ensure the LX2 will be powered after Lx1 and LX3.

It means, the EN2 will be powered before VIN2.

based on the testing, we found this circuit is working, and when VIN2 being powered, LX2 will be enabled after about 15ms, it is much longer than that between VIN1/VIN3 and LX1/Lx3( which is about 2ms).

Please help confirm whether this designing is normal and whether there is risk or not. 

thanks
