I'm unsure what it is you are recommending the OP to do.
The point is that loading kernel modules after a kernel update will not always work, so a reboot is in my experience advisable before you do any configuration changes involving module loading.
Such config changes might e.g. be firewall changes or new hardware.I don't know if Pascal's description of the condition is accurate, the effect has been real on kernel updates in the past.
