Yes the fail safe isn't bound by the flow of time as it could activate in a place where time didn't exist yet, but the Chronosapien Time Bomb deleted Ben (and his Omnitrix) from ever existing. It's like going back in time and killing Ben's parents before he was concived preventing him from ever being born. The Time Bomb was like that but instead of Ben's parents, it was the entire universe. Obviously the current 16 year-old Ben's fail safe wouldn't activate in that situation because Ben and his Omnitrix would never have been created (I'm ignoring the Grandfather Paradox in this example). So the fail safe not activating for that and activating in responce to an explosion makes some kind of sense.

The fail safe isn't even unlikely in the first place as we've known one to exist since the Original Series. Back in the OS the fail safe only took itself out of recharge mode to allow Ben to save himself but Ben still had to pick and transform into something which took a second or so. Also in the OS the Omnitrix was shown to protect the wearer from Ectonurite posession too. To my knowledge the pop-up trivia confirms both of these events as well. Then there's UAF, which introduced the Omnitrix's revival feature as shown when Vilgax destroyed Ben as Chromastone only for the Omnitrix to bring him back to life as Diamondhead. The fail safe is very real.
