This is not necessarily true. For example, when "listings" package is
used, listings and floats get a different counter.

You can use @@html:Listing@@@@latex:Figure@@ [[lst:a]], or with a macro

  #+macro: listing @@html:Listing@@@@latex:Figure@@

and

  {{{listing}}} [[lst:a]]

As stated above, this is not always correct.

Counters in "latex" back-end are handled on the LaTeX side, unlike to
"html".

I'm not sure about what you mean here, and to what export back-end it
applies.

In any case, I don't think there is a single satisfying solution. It
really depends on one's needs. I guess we could introduce a variable to
switch from one counting system to the other, if needed. Patches
welcome.
