The buildings will have 2 sides parallel and 2 sides perpendicular to the
imaginary line passing through those 2 nodes you selected.
If you select a building which is not with 90 degree corners everywhere,
you will find there is more than one way/direction in which the new
building can be drawn.
It's quite versatile and it's almost never necessary to select 2 nodes like

>> Hi all,
>> For the JOSM users:
>> I tend to use the X tool, but both ways illustrated are great.
>> The only part of the text that does not make sense to me is where it says
>> in the "area intersections" method: "then select 2 nodes of that box"
>> My understanding and usage of the building tool is that if you select a
>> building as a way, you know, just click on the building to select it, then
>> switch to the building tool 'B', every building you draw will be parallel
>> to that selected building. That is what it looks like he does in the
>> animated gif demonstration.
>> If someone knows what the 'select 2 nodes' applies to and how it is
>> different than just selecting the whole building, I'd love to hear it.
>> Thank you for the tutorial Andrey.
>> Happy building mapping!
