And here is the sequence after lifting the remaining finger:

If the driver reports one of BTN_TOUCH or ABS_PRESSURE in addition to the
ABS_MT events, the last SYN_MT_REPORT event may be omitted. Otherwise, the
last SYN_REPORT will be dropped by the input core, resulting in no
zero-finger event reaching userland.

[3] The multi-touch X driver is currently in the prototyping stage. At the
time of writing (April 2009), the MT protocol is not yet merged, and the
prototype implements finger matching, basic mouse support and two-finger
scrolling. The project aims at improving the quality of current multi-touch
functionality available in the Synaptics X driver, and in addition
implement more advanced gestures.
