Exactly. TinyOS does not foresee the possibility to run multiple applications on the same mote in parallel (other than you writing the application logic to do this). Also, TinyOS (at least in the default configuration) does not have multi-thread support.
If you just need multiple applications on a mote, but would be fine with restarting the mote in order to run a different application, you could have a look at Deluge. With Deluge you can define multiple images (program binaries) and I think there is an API that allows you to restart the mote into a different image.
