Hi Petr, by the way you are probably curious about the "stick to surfaces" mode thing that was that extra line for v2 (and was causing the script error in v1 since v1 does not know about it).

That is part of the new on-surface drawing for v2.

A few commands tend to work better with that if they set an option in their command script to sort of reduce the amount that they automatically adopt an object's plane as the construction plane.

Otherwise there was kind of a problem where something like a mirror of a box was getting a feeling of kind of sticking too much to the box's own faces instead of mirroring in the viewport's construction plane. This mostly applies to some transform commands.
