There's really no 'special' seeding. They can obtain and use and Injury Protected Ranking. And IPR is used for ENTRY into an event, and not a seed.
However, the AO, as all Slams, have the authority to seed anyone anywhere they'd like presuming the player is in the Top 32 entered players.
Meaning, they could put #32 as the #1 seed if they wanted to. It's discretionary for each Slams' seeding committee.
