If I recall correctly, Garmins don't use the road name for links. Instead they use the name of the first non-link road, i.e. where the link leads to. So the first bit of the exit ramp stays as a link (road type 0x08 or 0x09), and a short bit in the middle gets the destination as a name, so the GPS will announce "take exit to Mytown". There may be more to it, but that is how I think it works.

Hi Alexandre,

my first guess was, that mkgmap uses feature called in cGPSmapper "road sign". This works similar to restrictions and needs multiple legs to indicate road path associated with road sign.

Now I rather think that destination hints are simply short legs of standard road inserted into road links. This configuration probably needs a link before inserted leg to generate required hint in GPS. That could be the reason for splitting links. I'm not sure, maybe someone can comment.
