I've been confused about this too... perhaps some modification to the interface would make it clearer. Different wording, or a mouseover with more instructions?

yes, 1024/1024 makes sense, but it's not like it comes into your mind when you want to resize based on just one ...

That is what I did. Actually, I set width to, let's say 1024, and height I left it blank.
