What you are looking at, is version 5 of that node. The problem is, that
version 1 was create by an anonymous user:

So, all later modifications are derived work from this inital edit and
are therefore incompatible with the licence change.

I assume that you are looking a the author tab. That only shows the author
of the last version and is therefore not very helpful for finding data that
needs to be replaced. You should install the licensechange plugin.

Yes, unfortunately, the entire part of the motorway needs to be replaced.

Again, even if you install the licencechange plugin, it might tell you
that the way is ok. That happens when the way that was originally created
by an anonymous user was split later by somebody. Then the history of one
of the two parts is lost. If you see nodes on the anonymous map remap
the nodes _and_ the way. (Don't forget to make new intersections. If you
simply delete the way, all nodes on intersection will not get deleted.)
