I think this is the same sequence, I will try to explain why the behavior is different.
It’s due to the slow movement, your steps don’t have the time to go to the end of the position.
In « normal » mode your initial position before you launch the sequence is maybe 50% x and 50% y and the moving head oscillate between 40% and 60% during the sequence
In live mode, your moving head are in initialized to 0% x and 0% y.
So your movement oscillate around 0% - 20%.
To fix it you can for example create a button on your dashboard with a preset that initialize your moving heads position before you launch your sequence
