In the early days that was common advice because there were issues that needed fixing and that was the way to get the latest firmware and kernel.
Now that the situation is more settled the apt-get upgrade will upgrade the kernel and firmware to a known good version.
rpi-update is now mostly used in the case when you have a specific problem and one of the RPF people suggest trying it.
You may be able to revert by doing "sudo apt-get --reinstall install raspberrypi-bootloader", which will reinstall the current kernel and firmware.
