Anytime our Congressmen get up to speak- they may just say a couple of the things they WANT to say- if they will add things later for the Congressional Record- they must ask permission from the Speaker.
So- at a later time if they want to add a longer speech, a newspaper article etc. they are granted the right to do so. They often say it during debates on the Floor so they can come back to finish later. However- they don’t stand side by side, shoulder to shoulder, in an unbroken line to stand at the podium to ask for permission to revise and extend...
What they did was clever as well as visually perfect showing a unified front :)

One-Minute Speeches

Debate on RULES, GENERAL DEBATE and AMENDMENTS CONTROLLED under a RULE
HOW? Request time (in advance, if possible) from the resolution/bill/amendment Manager.
WHEN? When the Manager yields time, walk to a microphone and begin your remarks:
I thank the gentleman/woman for yielding. I rise in support of (or opposition to) the resolution/bill/amendment and ask unanimous consent to revise and extend...
Thanks.
