Though not related to Org, I noticed that ess-make-buffer-current calls
(update-ess-process-name-list) thus making a call for it in my-ess-eval,
probably, somewhat redundant, right?

Another thing that somewhat bugs me is that if R process quits (or
probably dies as well) when editing source code block in a separate
buffer, the subsequent S-RET will silently execute a line in a wrong
buffer/process. If there are no buffers with R process, it will create
the default *R* named buffer. It might be exotic but I think it is an
issue.

Does it mean that there is a bug in ess-make-buffer-current function
somewhere? Something, probably, re-associates a buffer to another
process, does it?

I think it might be relevant that code editing buffer local variable
ess-local-process-name is non-nil when associated process quits. This
results in first ess-make-buffer-current in my-ess-eval silently
launching *R*.

I'm not sure if it is too much to fix. Perhaps hitting C-c ' twice to
re-start editing is a reasonable workaround.

Where is org-src-in-org-buffer macro defined. Searching all dot el files
in org folder does not show anything neither does C-h f show anything
similar.
