Yes, the secondary floats to keep axial force off the jackshaft bearing.
There are a combo of spacers on the bolt that determine float, and spacers behind the secondary on the jackshaft that determine offset - if you pull the secondary, pay attention to the jackshaft spacers, you don't want to lose them. The offset spacers and float spacers work together to provide clutch alignment and system durability. If you were to change the offset, e.g., you would also have to adjust the float.
