A general Stata issue: stuff listed by -estimates list- 
is ephemeral and will get overwritten by the next eclass 
command. The alternative is that a series of models 
fitted in succession would leave a series of matrixes 
behind them, in which case they would need different names. 
It is up to you to make the ephemeral permanent 
by copying e.g. 
. mat b = e(b) 
after which such matrices would be visible through 
-matrix dir-.
