I totally agree and I want to add that for me, I keep shoulder blades pinned in and down the entire time but I do not cave my chest.

Also, I find it much better on the ROM to over arch my back at the bottom/stretch of the movement. I do not over arch my back during the pressing/contraction of the movement. The arch helps with the stretch and ROM, but does not benefit the flex at all.
