God I hear that. In this context glare obviously means "reflected light that makes it difficult to read."
He believes incorrectly that we should exclude coherent light (i.e., forming an image) in assessing glare. Now, the touchscreen must add reflection by simple arithmetic. As light passes from one medium to another, be it from air to solid or between solid layers, the difference between the indices of refraction of the adjacent media creates transitional phase differences, increasing the amount of light reflected. These reflections are cumulative, and can "wash out" the display, making the underlying image unreadable.
So when you see a comparison photo of a 600 with a big white halation vs a 505 with a smaller one, he is saying the 600's is more an actual image of the light source whereas the 505's is proper glare.
He is confused and making the wrong distinction between reflection and glare. "Reflection" deals with both internal and external sources of reflection, whereas "glare" deals with only external sources of reflection off a surface (e.g. bright sunlight or high ambient lighting conditions)
regardless of whether the reflected light is coherent. In fact, anti-glare coatings use diffusion mechanisms to REDUCE the coherence of the reflected image.
But Polly still wants a cracker I bet.. <sigh>
