I always assumed that was an admiral who unlike most didn´t ascend through the usual command/career path (like Worf who switched from yellow to red when his duties changed) but rather stayed inside his division and ascended there through the ranks. Seemingly rather uncommon but not unheard of.
As for Bones, he was probably already retired and only a VIP guest because he served as CMO on two of her predecessors.
Either that or he pulled seniority. Remember the tantrum he threw with the transporter in TMP and then imagine the unspeakable things he´d do to a twenty-something Lieutenant who´d dare try to instruct him on stuff like dress code regulations. Would probably be stuff that only appears in the darkest of Klingon nightmares.
[edit]And why exactly is a discussion about an admiral from a DS9 key episode in the TNG section?
