I think this depends on the server configuration. OpenSSH servers by 
default allow creating more channels/sessions per connection 
(MaxSessions default is 10 in sshd_config), but if you connect to other 
SSH implementation or if somebody configured the server not to allow 
opening more sessions/channels, then this might fail.

Please, review the server configuration, but if the server 
configuration/implementation does not allow this, there is nothing else 
you could do. Only run all the commands as part of the shell as 
mentioned by Andreas previously.
