Actually, this is knitr (which rmarkdown Imports) at work. There are options
as to how knitr will handle multiple plots in a chunk as described in

So this applies to various filetypes in addition to *.Rmd (*.Rnw, for one).

Getting babel to handle this seamlessly would be a significant effort.
You can use ox-ravel (https://github.com/chasberry/orgmode-accessories.git) to
export to *.Rmd and then render the result. However, that does not have the
interactivity of `org-babel-execute-src-block' and does not insert the graphics
into the *.org file.
I suppose that a function could be created to narrow to the src block, export
it as *.Rmd to a buffer, run that buffer as the `text' arg of knitr::knit, then
add links for the png's back to the *.org file. I haven't thought much about
this - getting this to work in a simple case would not be too hard, but there
may be a can of worms that this approach opens.
