This is a distinction with no technical value. Waves in the same
location are subject to the usual rules of linear superposition of the
fields. Whether you want to call this "interference" is simply a
philosophical choice. There is a whole gamut of results resulting from
the superposition, ranging from zero field to a maximum of all the field
magnitudes combined. The terms "destructive" and "constructive" are
sometimes used to denote the extreme cases, but those terms are not so
well defined for the more intermediate cases.

There is utterly no scientific distinction that applies to "signals
traveling in opposite directions." The mathematical results may look
special in the opposite direction case, but the same basic equations
apply in all cases.
