Hi Marian,
Just a wild guess:
your QGIS project might have a different coordinate system than the
layer you are editing in. This might explain different coordinates.
But - not having access to your project, I can't examine that.
The other thing to check:
feature = layer.getFeatures.next()
Is this really returning the feature you just edited? Note that there is
a QGIS plugin called "Plain Geometry editor". It allows you to click on
a feature in the canvas and return their coordinates. In newer QGIS
versions there is also the vertex editor panel with a node list showing
an active features geometry. But not sure if this existed in version
2.10 - which is already quite old.
Greetings,
Andreas
