Your point seems quite reasonable to me. Just before Rick had his 3-state sweep in the Midwest there was a rumor that both Newt and he had agreed that everyone should stay in the race as long as possible. Sarah has been echoing that sentiment for several weeks; so, that's good enough for me.
I believe that agreement was likely “unless one of them pulls ahead of Romney for x number of days.” With one of them now beating Romney, it could prove interesting to see how things play out.
