It looks so, i would say if you have coins on exchanges - withdrawal to your account. The snapshot can come any moment.
This way you make sure all will be swapped/doubled.
I am not sure about tokens on Steem-Engine but for sure community will not let them be gone.
Today not a marketing post per se (unless you can say that about Call to Action about withdrawals).

The snapshot happens when you want it to its not all accounts at the same time
