With my environment (^) appears the additional blocks are added in step 2.  After 'shingling' one half of the roof (via inserting blocks and "Move/Copy"), I saved just the shingles to a separate file and then imported it as a block for the second half of the roof.  The number of blocks went from three to 30+ (I only partially shingled the roof).  If you 'Move/Copy' the first view to create the second view you could avoid the problem.  As noted previously, Copy & Paste ([Ctrl]-C / [Ctrl}-V} will also cause the blocks to multiply in the block list.
