Something like that. The whole premise of "Generations" -- something tantamount to time travel, but using "the nexus" -- creates a ton of logistical problems. James T. Kirk is a legend. Captain of the flagship for years, promoted to Admiral, busted back to Captain and thus the captain of the flagship again, then in a bizarro event he is "killed". Gone.
But it turns out he's not killed, he's just in "the nexus", and 80some years later, Picard convinces him to leave it so he can help make a difference again. Except they don't really tell anyone. There's no press release, no celebration honoring the return of a legend, they just go off and fight Soran. So when Kirk dies, actually dies this time, what are they gonna do? He's been "dead" for... generations. What can Picard do? Tell everyone that Kirk wasn't really dead all this time, but, um, sorry he actually is now?
Kirk always said he knew he'd died alone. He wasn't quite alone; Picard was there, but basically yeah, no one else around, and no real memorial. It was weird how it played out, but my guess is that you're not really supposed to think about it. Which is lame, but there you go.
