TUSB7320: TUSB7320 Power Sequencing

Part Number: TUSB7320

The datasheet of the TUSB7320 recommends to apply 3.3V followed by 1.1V. The board I am working on does the opposite of this (applies 1.1V rail followed by the 3.3V rail ~1ms later). The hub still comes up just fine, however, I was wondering about the longer term effects of powering up the hub in this reverse sequence. nGRST is held low during this time until both rails are up. If you could provide some additional information on what happens if the recomended power sequence is not maintained for this part, that would be very helpful.
