I did the same as you and blindly followed the steps to register my EOS on MEW, worrying that I might do something wrong and lose them all or even worse, think I had done it right but find out when the token sale is finished that I didn't and be left with worthless tokens.
I am pretty sure I did it right and might have even done it twice to be doubly sure but after reading this I am tempted to transfer them from my MEW to Exodus for peace of mind.
Thanks for the info.
