Nope, Mythbusters thought that too, and they found out that the floating door could actually have carried both of them without sinking, when they were careful. Then they added the life jacket one of the two in the movie was wearing to the door, to keep it afloat, and they had no problems at all. So basically Jack died for nothing.
