I am straining my limited brain power to answer this question but I think the question revolves around a possible difference between a min flap retraction speed and a minimum maneuvering speed.

A poster speaking on the A320 is correct in that the min maneuver and min retraction speed on the bus are the same. Green dot is that speed. However, on the B737 for single a engine go-around there is a lower speed for flap retraction and acceleration that is maneuver limited. You are limited to 15 degrees of bank.

So my answer is on departures and especially on single engine go around there may be a lower speed to select flaps up but that condition is maneuver limited until you have reached the min maneuver flaps up speed. I think this is to improve single engine governing weight limits etc.
I don't know the technical definitions however.
