Converting CMYK solids to Pantone in Illustrator

Hi,

Theresa Jackson hosted a wonderful presentation for Adobe of Recolor in Illustrator this week. 

Here's a link to part of it:

That really is great tip and would save A TON of time, some clever helpful programming right there - but I have a question   - when would one want to do that?  When it comes to printing that art it's plainly impossible to put that many special colours on a press?   (this a printable document, right, because Pantones are about print?)

am I misunderstanding? 

thanks
