[Elecraft] P3 Update question

[Outlook.com via Elecraft]

Hi,

I have a question about downloading P3 firmware updates.  On the website's download area for P3 there is a comment in ( ) that says to download with K3 firmware above.  What does this mean?  

Does it mean that I should download P3 firmware anytime I download K3 firmware, or something else.

Both of my K3s and P3s are up to date.  Just curious.

Elecraft is great.
