IIRC, young Robert spent most of his days out working in the fields, tending the winery. Jean-Luc was much more of an indoor kid. So it makes perfect sense that Yvette confided in Jean-Luc more than Robert; thus, Robert wouldn't be part of any of these flashbacks.
(Likewise, I suspect that Maurice got along better with Robert than with Jean-Luc, because they were more alike as well.)
It's like Quark and Rom on DS9. Quark always took after Ishka, while Rom was much more like Keldar.
