No, it'll work. I have Jeanne's word on it, not to mention I just tried 
it. :) When you are sorting cards, "this card" refers to whatever card 
is currently being considered for the sort order.

In Revolution, that's two things. Sorting and going are different.

No; you can be on any card. Try it. Sorting the cards is Thing One.

Going to a particular card is Thing Two. Sorting does not depend on what 
  card you are on; the sort takes place independently of your current 
location. The sort process considers the value of the sort key for each 
card in the stack, and reorders them according to that value. You can 
sort by your custom property no matter where you are currently located 
in the stack.

Consider, for example, sorting by the value of a field:

  sort cards of this stack by field "lastname"

The sort process considers the value of the field for each card, and 
orders them appropriately. Another example, from the docs:

  sort cards by the number of buttons

"Of this stack" is assumed. Rev considers the number of card buttons on 
each card in the stack and uses that number to rearrange the cards.

  sort cards by the myValue of this card -- this is the one you want

"This card" refers to whatever card Rev is currently working with during 
the sort process. Rev considers the value of the custom property 
"myValue" for each card, and sorts the cards according to those values. 
This will restore your original sort order.

None of these sorts has anything to do with your current location in the 
stack, nor does any sort take you to a particular location when it is 
done. Navigation and sorting are two independent processes. When you are 
done sorting, you'll probably want to make use of Ken's card marking to 
find the card you want to go to.
