That sounds a lot like Wilhoit's formulation: "Conservatism consists of exactly one proposition, to wit: There must be in-groups whom the law protects but does not bind, alongside out-groups whom the law binds but does not protect."
Barlow is talking about a tendency for people to have difficulty reacting to change that occurs within their lifetime. They may have fought for change when they were young, but they get attached to the specific changes they were fighting for, rather than to broader principles.
Robin is talking about a broader cultural phenomenon, where some people feel entitled to rule, and present some historical time when they did rule as utopian. That is often not entirely backwards-looking. They don't just want the ideals of their youth, but a broad set of changes that will entrench their power and suit their personal tastes.
The backwards-looking language can be similar, but governance they propose is very different. Confusing it further is that many "revolutionaries" are in fact conservatives, trying to take power for themselves even while claiming to represent broader freedoms.
Among other things, this makes it hard to discuss the Russian revolutions in progressive/conservative and left/right terms. The entire thing ended up just entrenching a different conservative power base, who used progressive language but implemented little of it.
