Looks like your script creates multiple output records, so if 

l100107,bbbbbbb,c_0300,loc,12,6
in FileA matches 
l100107,bbbbbbb,c_0300,389
in FileB, the output is 6 lines (the value of $qtd the last column) 
l100107,bbbbbbb,loc,12,389
l100107,bbbbbbb,loc,12,389
l100107,bbbbbbb,loc,12,389
l100107,bbbbbbb,loc,12,389
l100107,bbbbbbb,loc,12,389
l100107,bbbbbbb,loc,12,389

Is that what you want ?

Also, can you please explain what this code line does.

last if $count == $max;
