The Range goes to the last cell in the first column ,A65536, and then goes to the top, A1. The Offset part of your code then takes you to the second row  first column.


Range("A1”).Offset(1, 0).Select would do the same thing.


Selection.Offset(1, 0) would take you to the cell below the current cell

And

Selection.Offset(0,1) would take you to the cell to the right of the current cell.
