Just to emphasize this another time: aliasing is no magic, it is NOT renaming. (And it is only supported for methods.) The important implication here is, that aliasing is only useful from the viewpoint of the composing class. Form the trait's perspective, aliasing does not have any effect. Aliasing can be used to make a function accessible that has a naming conflict with another function. It enables composition of traits, but does not do anything with regard which function names a trait-function calls. In PHP all function names are late bound, there is no inner binding between functions in traits. Hope that clarifies what I perceived as a misconception.
