It's my way of distinguishing between rounds and separating what is "surprise" from what is "regular" initiative. Once we settle into regular initiative rounds, we'll keep the posted initiative sequence. At least, that was my take on the beta rules passage on surprise rounds in the combat section when I re-read it again this morning. I can see a case for having surprise round initiative and regular round initiative separate, but I can also see a case for using the same initiative throughout.
If someone can show me in the beta rules where it states that we are supposed to keep the same init throughout,
OR if all of you prefer to keep the same init throughout, I have no problem doing so. Less rolling for me.

Let me know.
