That's how I interpreted it as well.

So if the salt flat is the ocean floor, then there should have been a several kilometre drop just before it. Also, even if the entire earth is desert, 160 days is still more than enough to circumnavigate the earth.
1. This might be getting into too much detail.
2. They definitely wouldn't be able to circumnavigate the Earth in 160 days or any amount of time because there are no roads or gas stations on the bottom of the ocean left over from Before. Even if they brought their own gas and had reliable off road vehicles (they probably had the last at least), doing 250km straight line treks every single day for half a year seems almost impossible.
3. Even if they managed to circumnavigate once, they wouldn't know it. Unless they hit the exact same spot they started from (which seems astronomically unlikely), they would just keep seeing new places so they are still going "forward" from their perspective.
