REPLACING TIMING BELT

1998 Lexus ES 300

Engine Mechanical problem
1998 Lexus ES 300 6 cyl Front Wheel Drive Automatic 131000 miles

When aligning the installation marks on the timing belt, crank is at TDC and both cam sprockets are aligned with timing marks.

After installation, when you turn the crank two revolutions, should the installation marks (not the timing marks), line up again?

The book says to turn the crankshaft thru two complete revolutions, then the timing marks line up again at cam and crank, but the installation marks on the belt don't. Is this OK? Are installation marks only important when installing the belt, and then I don't need to worry about them, as long as timing marks line up?
