I can reproduce that and have identified the cause. Our algorithm for
calculating the intersection of two pseudo-ports does not respect the
order of the items correctly. Or more generally, it is wrong if a port
name appears more than once in one of the two lists.

This code is in opIntersection in base/src/port/port.tcl [1]. First, it
creates a map from the port names to the list index in $b. If a port
appears multiple times in this list, the last index is stored in the
array. This is clearly wrong as we would want to keep the first entry.
