Isn't the answer that the liberated one never thinks of him/her self?
This is one of the reasons why Buddha always referred to himself in the dialogs as 'Tathagatha', 'gone thus'. There really is *nobody* who has gone thus. There is no 'enlightened person' as such. Of course this is somewhat baffling and paradoxical to the normal mind.
Also bear in mind the 'undetermined questions' - those questions about whether the Buddha continues to exist after parinirvana (or not, or both, or neither) and the various other questions about whether self exists (or not, or both, and so on.) There are about ten in all. These are aimed at preventing speculation and attachment to ideas which form the basis for beliefs about things that are 'out of range' for knowledge.
This is why the emphasis remains on practice and direct perception of the causes and conditions of suffering, not theories about some ultimate reality. Which is not to say there ISN'T an ultimate reality, just not to speculate....
