I had a vague recollection of something like that, but it's not true.
The algorithm is

 - remove the final post-slash segment of the base
 - append the relative uri
 - remove dot segments
 - remove dot-dot segments
 - if there are dot-dot segments left (which must be at the beginning)
   it's an error

All this only happens if the "relative" uri has a path not beginning
with slash.
