Probably,
But, what if the implosion happened not long ago
They had almost reached the Titanic when they lost communication so they were already close
And where they found the debris close to the times had it back then up
So what if they lost power when they lost communication and have been sitting on the bottom all this time
And all the pressure for days finally imploded it
What if the banging they have been hearing for 2 days where the passengers banging on that see through 7-in glass trying to break it and end it all quickly instead of suffering, and finally succeeded
The guy who has been to the Titanic wreckage a few times was just interviewed recently and talked about how they would have no chance to live if they ever lost power
If happened I'm sure he explained all of that to the others and they could have made a decision
Who knows
