I'm not quite sure what you mean. When you die and use a soul gem to revive, that soul gem is then gone - it doesn't just empty and is then eligible for use again. It has always been like this, or at least for as long as I have been playing the game.
Of course I'm on PS4 where U25 hasn't dropped yet, but again, I can't say that I've ever noticed soul gems reappearing empty after you use them, so I don't think anything has changed there.
This poor little Bosmer stealth passive had passionate friends and a big loving family!
