As I expect, wrong description. Sorry

Once more. On this screenshot is what I'll describe
http://locus.asamm.cz/data/screenshot02.png

1. I have one Path object with a complex path (as I walked and
recorded path with GPS).

2. I draw this one Path object on canvas with
c.drawPath(path, paint);

where paint is Stroke, semi-transparent blue, width variable (now cca
50px)

3. I also draw second time same Path object with simple slim black
color, 1px width, to see exact way I walked.

You can on screenshot see, that all places have same blue color, even
when on same place is path more then once. Clear? Xfer as I tested
have no influence on this. It only works when I for example separate
whole path object into more path objects, then color overlay work and
on places where is more then one line, blue is darker. But it's really
weird solution, manually separate path on straight lines.

Is there anything I'm missing? Thank you for time to read this!
