I agree with Timothée that it looks like “name dropping” to a degree at least. There are certainly some scansion problems whose solving requires knowledge of what Greek was like before the advent of the alphabet, but how many of these problems were solved with the help of Linear B sources? Most of them, I think, have been solved with other linguistic methods. (see e.g. this http://discourse.textkit.com/t/homeric-meter/13945/2)
But seriously? They find a generic battle scene on a seal, and immediately it “evokes tales from the Iliad and the Odyssey”? There wasn’t strictly anything in the article to allow us to recognize which heroes might be depicted, or which battle. I actually spotted one thing that was clearly unHomeric: the fighter on the left has his scabbard hanging from the waist from a belt. Homeric heroes hung their swords from their shoulder with a baldric (e.g. Odyssey book 2 line 3). The fighter on the right seems to have some sort of baldric on his right shoulder, but I don’t know whether it’s to hang his sword or his shield. (Homeric heroes’ shields didn’t have elbow straps, but they hung them from the shoulder - one shoulder for the shield, the other for the sword.)
