Strange ssl_client_certificate limitation?

[Rene Moser]

Hi

I have a hard time with ssl_client_certificate.

I try to use vhosts with 2 separated CA in ssl_client_certificate 
configs but I was not able to do it as expected. The later 
ssl_client_certificate was not taken in effect and even more unexpected 
I was able to use the first client cert to auth in the seconds vhost.

To show the limitation, I created a reproducer:

Please tell me I did something terribly wrong.
