Eh Luke, Ulic and Vader all employ Form V lightsaber combat and Ulic was a prefiguration of DE Luke as the author describes, comparing them as excellent swordsmen. In reality it is just confirming their status as the two greatest swordsmen of the OR era and two of the greatest of all time, now we simply have an indication of their tier.

I thought Tom was comparing Ulic to ROTJ Luke. That's still a good feat though. Kun takes this.
I thought so to but then I realised that he called Ulic a prefiguration of the Luke Skywalker he was designing and writing, which is the Dark Empire version. They even share the same character arc through both stories, they both attempt to infiltrate the Sith, fail and join them and are then redeemed in some way.
