The feuille translates as leaf
Inverse translates as inverse
So we have an inverse (inverted ?) leaf style / concept ??This might refer to a decoration or structure utilized within the recipe for assembly or garniture.
The leaves might refer to Mille Fois too. . .
Or, maybe, there is something being done with Phylo???
Perhaps if more of the recipe were provided, we, or another within our midst, might come up with something.
My bet would be Chef Eric, I have great respect for his offerings, as I have read his contributions elsewhere.
