You might be mixing things up with another model that is estimated in
Stata as -heckprob-, when the binary dependent variable of the first
equation is used as an explanatory variable in the second equation.

-biprobit- just says, "There are two outcomes that are affected by
exactly the same regresssors". It is similar to -mvreg- where you have
multiple continuous outcomes.

Does that mean that you can treat the endogenous dichotomous regressor as exogenous when you estimate the two probits separately?  In other words, is rho a de facto exogeneity test as well?  My understanding is that you can include the observed dichotomous regressor on the rhs, even though its endogenous, BECAUSE you are estimating with a bivariate probit (Greene 2003, p. 716).
