For each touch event touches array is filled with all the points that are touched. And I have notices that in case of tizen Z1 phone, this array goes to max length 2..
FYI: I am using jQuery touch event handlers.

mouse only supports a single point. not 2. it won't be that. at least in the
layer presented to webkit it gets mouse events for the first touch point, and
multi events per extra touch point after that (with an id number per multi
event to tel you which touch point it is).
