That's the (only) correct behavior.

Sadly, a NO response from SELECT requires that an UNSELECT be done; this 
is the result of a mistake made in RFC 1730.  Nevertheless, this can only 
happen because the command was recognized.

BAD means that the command isn't recognized due to syntax problems.  In 
order for a SELECT that returns BAD to have UNSELECT semantics, there 
would have to be some sort of requirement that an unrecognized command be 
"half-recognized".  I hope that nobody wants to go there.
