A port can easily fetch multiple distfiles if necessary, however  
MacPorts only runs each phase (configure, build, destroot) once, and  
making it issue multiple configure and make commands in multiple  
directories basically requires reimplementing those phases yourself  
in the portfile, which is a lot of work to do correctly, taking into  
account all the features we have in MacPorts for nice builds and  
parallel builds and universal binaries and such. Easier to just make  
them two separate ports as you said.
