What does vPos(2)(1) means?

Hi

I read the API help on" Reposition Drawing Views to Avoid Overlap Example (VBA)"

http://help.solidworks.com/2012/English/api/sldworksapi/Reposition_Drawing_Views_to_Avoid_Overlap_Example_VB.htm

and saw the command line:

'View 2 - vertically aligned to view 1 

Set swView = swView.GetNextView

vPos(2)(1) = vPos(1)(1) + _

(vOutline(1)(3) - vPos(1)(1)) + _

(vPos(2)(1) - vOutline(2)(1))

swView.position = vPos(2)

What does the number (2)(1) in vPos(2)(1) represent? I couldn't figure out how the additional and subtraction align the views.

Please advise. Thank you.
