The ADV7180 Power-up Sequence question

In one of the later revisions of the ADV7180 datasheet a section on power sequencing was added.  While I have had a board designed using the ADV7180 and the ADV7391 for a while, I have not used it in the entire system until recently.  I was curious as to why the Power Supply Sequencing section was added?  What sort of problems occurs without these steps?
