They're referring to G-level canon which is George canon. Even if they weren't while I appreciate Splinter of the Mind's Eye for what it is, there's not a lot in it that can easily fit with the rest of the EU.

They say "canon", not "G-canon", which implies very clearly that Splinter is not counted as "canon" at all. I see no proof there that they're just referring to just G-canon. It sounds very much like dividing between canon and non-canon, rather than dividing between G-canon and lesser canon. The EU-is-canon viewpoint clearly stresses that lower levels of canon are still canon too, which is at odds with the quoted statement that simply implies EU isn't canon at all. If they were going by the Eu-is-canon approach they wouldn't word it so as to clearly imply the EU isn't canon. What you've got there is somebody writing who doesn't consider non-Lucas material to be canon. By very nature the wording implies that non-Lucas material is not canon. They do NOT go and specify G-canon, which they would do if they were somebody going by the G, C, etc system of canon.

You have to remember, Lucas himself doesn't take the canonical status of the EU seriously, so it makes sense that some of his employees would dismiss it too, even if some others are busy promoting it as canon.

As for Splinter itself, it's been counted as canon by Leland Chee, who runs Lucasfilm canon (the "canon" that calls EU canon). So it's as much "canon" as the rest of the EU, whether it fits or not.
