disolve menu option

In the right click menu in the code editor on a Do together or Do in order there are delete and disolve options that seem to do the same thing. What's the difference?

[pausch]

Dissolve takes all the lines of code in the DoTogether or DoInorder and "dissolves" them into the code at that point, basically "freeing" them from the DoTogether or DoInorder.

If the DoTogether or DoInorder is empty, then dissolve is indeed the same as delete.
