Confirmed.  There's a bunch of conditional code in intersect.m to handle the "stable" flag so it is easy to see how something like this could creep in.

The third output in "intersect" with the "stable" flag is not correct. For instance, the output of the following command

[~,~,IB] = intersect ([8 4 2 6], [1 7 2 8], 'stable')
IB =

   3
   4

should be

IB =

     4
     3

A similar issue appeared before for the "unique" function. See bug #46856
