I guess the main idea is that it is more likely for the text around the
link to remain the same: the line number can change (e.g. if you add
stuff at the beginning of the file), but the surrounding text will
probably remain the same, so a context search is more likely to find you
what you want. But you are right in that a line number can sometimes
disambiguate things, e.g. the etags functionality in emacs works
(worked?  not sure if the implementation is still the same) by using a
position to go to and then searching in ever-widening circles around
that position in order to find the appropriate context. That way,
identical contexts could be used (a necessity for etags) and still be
distinguished from each other.
