When you drag and drop textures into the transparency channels , Maya uses a different attribute to make the connection from texture to transparency channel depending on what type of shader is being used and so the shader will render differently, like the Maya standard shaders such as blinn vs a mia_material.

Other thoughts:
It's most likely because one is a vector attribute while the other is scalar, unlike the color attribute on the blinn and the mia_material's diffuse color, both taking RGB input and thus being vector attributes, so Maya uses the same 'outColor' attribute when connecting texture to shader.
