Hi Amos,

this is the expected behavior.  RefTeX comes with a variable called
`reftex-label-ignored-macros-and-environments' which you can customize:

,----[ C-h v reftex-label-ignored-macros-and-environments RET ]
| reftex-label-ignored-macros-and-environments is a variable defined in 
| Its value is nil
| Documentation:
| List of macros and environments to be ignored when searching for labels.
| The purpose is to ignore environments and macros that use keyval
| style label=foo arguments, but the label has a different meaning
| than a \label{foo}.  Standard \label{...} definitions are never
| ignored.
| E.g., TikZ defines several macros/environments where [label=foo]
| defines the label to be printed at some node or edge, but it’s
| not a label used for referencing.
| Note that this feature is only supported if you are using AUCTeX
| and the functions ‘TeX-current-macro’ and
| ‘LaTeX-current-environment’ are bound.  Also note that this
| feature might slow down the reftex parsing process for large TeX
| files.
| You can customize this variable.
| This variable was introduced, or its default value was changed, in
| version 24.4 of Emacs.

Best, Arash
