Usually when first engaged, you deal with operational issues (making sure all the applications they know about are assessed), but as you build on that, you try and instill secure development practices (so that every new application they build doesn't have the same issues as the ones you've just spent months uncovering).
The number of large clients I work with who don't have any SDLC process is staggering (I'd say it's the overwhelming majority of them). For the most part, the small group of security people are tasked with trying to secure the multitudes of applications which in many cases are 20-30 year old codebases. Their developer groups may be completely separate (usually from the result of all the mergers of financial institutions) and it's basically all fiefdoms.
As you start to work up the pyramid of enterprise security "hierarcy of needs" you get to things like a secure development life-cycle, but not all organizations are "ready" yet for that type of work. Some are just trying to figuratively stop the percieved bleeding.
A bank will have architecture and security teams that evaluate the applications, but their main job is to run each application through a "best practices" checklist or audit to identify potential trouble spots. An application will need to meet some kind of sane minimum requirement for password security, but many of these apps are legacy or mainframe, and not easy to change. Big banks move very slowly.
This tendency is independent of the fact that these functionalities are implemented by different teams, and that one team might happen to be competent enough to do the right thing despite the lack of institutional imperative. So the consumer might get lucky. So what?
Your initial comment was that "plenty of financial institutions" do SSL a certain way, and the respondent correctly pointed out that this fact adds no information to the discussion about SSL techniques, because plenty of financial institutions do dumb things. It's "apples and oranges" only insofar as he's saying the orchard manager is a poison spreading dummy so you can't trust the apples or the oranges.
Maybe you can elaborate on the "studied" part of your comment with specifics. That part was interesting.
