<p>Since you asked... I call this update chaining.
<p>And it reminds me of the old story about demonstrating the "new" features of a word processor (I heard it about the old WordStar, severely dating myself...) The person shows her boss how you can change "all the 'a's to 'e's in a document." They then say "...and you can change them right back the same way. Uh. Oh." Of course, at this point, they discover that the Undo feature only backsteps one event. :)
