Since they're talking about the "import" maybe they're not talking about from the halted state? Maybe just the initial `vagrant up`?

That's correct. Each time you make a new VM, instead of copying the base box's disk image it creates an new disk image that will only store the differences between your VM's disk and the base box's disk.

Any idea how this feature will work with base box's images that are regularly updated? I've been using ubuntu/trusty64 and it seems to get an update at least once a week.

Base boxes are versioned. You have to keep the old version around if you have any VMs using it.
