[postgis-users] Point on a surface doesn`t touch geometry?

Dear users,


with "SELECT astext(pointOnSurface(the_geom)) from ways where gid=14730"
I get the coordinates of a point that lies on the surface of a MULTILINESTRING.

I get: POINT(897169.996155569 6850066.73917209)

Then I try 
SELECT overlaps (the_geom,Geomfromtext('POINT(897169.996155569 6850066.73917209)',900913)) from ways where gid=14730;

...and I get FALSE ???

(I also tried with "touches" and "intersects" --> the
result there also FALSE).


Has anybody an idea how this can be?

Thank you very much, Kai
