SACS: Tubular joint check with Launch Runner Section

How does SACS perform tubular joint check with launch runner section? In launch runner section, upper part of the section is normal tubular section which may connect to tubular braces, hence, normal tubular to tubular joint check should be checked by the program. Is this really the case or the program simply treat the joint as non-tubular connection and ignore the check?

Appreciate clarification on this. Thanks.
