just a coincidence ; for this to happen you need the blitter to require 
more than 64 bus accesses to draw the line in order to switch bus 
between cpu/blitter/cpu/blitter/...
So with a line that take 100 pixels or more, the problem is more likely 
to happen.

If you use a much higher vertical resolution (hi res for example), 
problem would certainly be visible in top third/quarter of screen, 
possibly doing the bug several times during one vertical line..
