I don't agree.

Walibi's website also says nothing of an inversion (or of the element itself). The turn is overbanked because of a quick diving turn that must be made after the hill is completed (there would not be enough room to bank and turn after the top of the hill).
The only "overbanked turn" that is considered an inversion is a cutback. Drachen Fire had one, and Space Mountain DLP has one (known as a "Tongue"):

No other overbanked turns are inversions.
