He's refering to 4th edition as being unpolished, and dull. That means that Andor thinks that the previous version is not unpolished, and more exciting to read. Quite easy, don't you think? You don't have to interprete much into it to see that this is going to end like that.
Also, it's an open secret that Andor belongs to the 4th edition critics. Heck, he even admits it in the very first posting above.
4th Edition Critic doesn't have to mean Edition Warrior.

People can find every edition of D&D lack luster and still be a 4th Edition critic. Heck, people can even like 4th Edition and be a 4th Edition critic.
Sometimes comparing edition makes sense (particularly if you want to understand or classify changes), but sometimes it doesn't (for example, if you want to know if something reads interesting or not.

)
Hey, look, a 3E spell written up in 4E edition style (but using 3E mechanics mostly)
