In theory, this depends on the OpenSSL library behaviour and may
work as long as SNI is used - nginx does it's best to update all
SSL options on SNI callback.

With current OpenSSL code it doesn't seem to work though, as
protocols allowed are checked before SNI callback happens and not
rechecked afterwards. So yes, you are right - "ssl_protocols"
won't do anything good in non-default server{} blocks, even if SNI
is used.
