As far as I know, we haven't decided on a different scheme.

Installing different versions is quite easy, it's just a matter of
using --prefix and --openssldir properly when configuring. Since it's
probably the binaries that you have problems with, you probably want
to use --prefix only.
Now, for OpenSSH this won't matter at all. What they do is compare
the value of OPENSSL_VERSION_NUMBER (a macro, which means the value is
built into OpenSSH at compile time) with the result of calling
SSLeay() (a function that returns OPENSSL_VERSION_NUMBER, the one that
got built into libcrypto). Therefore, any version change, including
patchlevel changes, will mean OpenSSH needs to be rebuilt.
I can understand OpenSSH's position on this. We have said for a long
time that before OpenSSL version 1, we don't guarantee binary
compatibility between edit levels (i.e. when x changes in 0.9.x).
Unfortunately, there have been cases when OpenSSL became binary
incompatible with older patch levels within the same edit level.
We're trying hard to avoid that.
