Hi,

The table is meant to depict the conditions when 'Hot-Scoketing' may be acceptable and what unpowered pins can tolerate.

The way I read the table is, for 3VIO banks 'Hot-Socketing' is Not Applicable. So, an unpowered 3VIO bank pin should NOT be driven to GND/VCCIO externally during power-up. During power-down, the unpowered pin and still be driven to GND but not VCCIO.

Hope this helps.
