I would say that it is the expected behavior: :float is for a float
environment and :environment is for the environment that builds the
table (by default tabular). According to the manual:
#+begin_quote
The table environments by default are not floats in LaTeX. To make
them floating objects use =:float= with one of the following
options: =t= (for a default =table= environment), =sideways= (for a
=sidewaystable= environment), =multicolumn= [...] and
=nil=. In addition to these three values, =:float= can pass through
any arbitrary value, for example a user-defined float type with the
=float= LaTeX package
#+end_quote
and (for :environment):
#+begin_quote
Set the default LaTeX table environment for the LaTeX export
backend to use when exporting Org tables. Common LaTeX table
environments are provided by these packages: tabularx, longtable,
array, tabu, and bmatrix. For packages, such as tabularx and tabu,
or any newer replacements
#+end_quote
The difference is that with images, except in cases of somewhat more
complex constructions where there are subfigures, there is only one
environment, "figure" by default or any other arbitrary one. There was a
commit a while ago, I don't remember when, that allowed :float to
support any arbitrary string as the float environment name, in images
and tables. In images ':float t' is figure (by default) and in tables it
is table (also by default).
Update: ah, I already have the commit located, because I also remember
that I myself sent a patch to update the documentation and correct a
regression that that commit introduced (:float t produced an environment
"t" (\begin{t}...\end{t}):
