Clearly some correlation was done between what Mangold & Co were doing and what Singer and his team were cooking up. Imagine The Wolverine
didn't originally end with the Adamantium claws torn off. Leave a quasi-dangling plot thread to be resolved/further explored.

Singer addressed that (in a round about way in lieu of Wolverine
's ending) at Comic-Con regarding changing continuity.
"Umm...whenever you are going back in time, and this is every bit as much a time travel movie as it is an X-Men movie. Uh, you-you-there is those risks. And so--and yet there are certain--yeah so some of that is going to happen and yet there are some things that--umm--you know if you believe in certain physics and multiverses and then umm--things like that and uh--then you also have a respect for the continuity as we have it. But mine is--is--I'm less so entrapped in those previous films and again I'm not the audience I'm just the filmmaker but I do believe in certain continuity that we will maintain but some things will change. It is the nature of time travel. You go back and mess about. Things happen."
