    There is definitely some interaction going on here. Don't know about a new or old galaxy. Don't even know what you mean about new or old galaxy !

    I guess, that he means following.:

    new galaxy= early-type galaxies (ellipticals and lenticulars)
    old galaxy = late-type galaxies (spirals and irregulars)

    He might be right, that it is a merger of an ETG with a LTG. To recognize the morphology of interacting/merging galaxies is sometimes difficult.
