In this note, we discuss the definition of the S₁-convexity Phenomenon. We first make use of some results we have attained for

in the past, such as those contained in [1], to refine the definition of the phenomenon. We then observe that easy counter-examples to the claim

extends K₀ are found. Finally, we make use of one theorem from [2] and a new theorem that appears to be a supplement to that one to infer that

does not properly extend K₀ in both its original and its revised version.
