IIUC in that case a `display-buffer' following another would wipe out
the variable set by the former.  The problem is with recognizing whether
the buffer `display-buffer' is going to replace in some window was a
buffer the user switched to "manually" or "automatically".  In the
former case `display-buffer' should remember the buffer in its
`old-buffer' variable while in the latter it should leave that variable
alone.  Currently `display-buffer' has no means to distinguish these
cases.
