The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). In case of a suspend/resume, the device switch back to the first mode described above (with left and right buttons). This adds a hook in .reset_resume for the device to be switched to the correct mode (I just copied the code in mosart_probe).
