Watching the SpaceX video RADARSAT Constellation Mission after
T+ 52:00 we can see at least the first two satellites deploy.
In each case, the second stage rolls one way during release of one of the satellites then stops and rolls back the other way.
Why are the back-and-forth rolls necessary, and isn't it a bad idea to release a heavy, off-axis mounted payload in the axial direction during a roll?
If the deployment was radial like in some ISRO cubesats I can understand, but these are axial deployments but from off-axis locations. I don't understand what's going on with all these rolls, especially as the satellite disengages from the 2nd stage.
