Yes.

It is important so that we can make sure that all cleanups are executed before 
transferring control. For example, if serial settings have been tweaked by 
GRUB, they should be reverted to the original state. At least, this is 
considered to be a good manner. Another example is video settings. Let's say, 
GRUB changes video mode to show a fancy menu. Some operating systems may not 
work well in graphical mode, then GRUB must turn it back to text mode.
