The setFCV commands runs collMod on the every namespace during the upgrade procedure. The collMod operation has a side effect where the global CurOp profiling level and namespace is set to the most recent namespace and the highest profiling level observed. For slow setFCV operations, this somtimes results in slow operations being logged in the system.profile collection of the last database we ran collMod on (very likely non-admin).
