Arial and Tahoma both use what you call a “flying-join” where the lower leg supports the upper arm some distance from the vertical stem. Times New Roman and Palatino both join the stem at a sharp point. Garava uses a smooth angle bracket connection to the stem.
The arm and leg may also be disconnected from the vertical stem as in Constantia.
