Question about head installation

So im in the process of putting new head gaskets/new head bolts in. Found this info on torque specs/order.. one can someone let me know this is correct and explain the 90 degree after 22 lb ft. Does that mean tighten 90 degrees more after 22 lb ft?

info i found

Tighten the cylinder head bolts.
Tighten the M11 cylinder head bolts a first pass in sequence to 30 N·m (22 lb ft).
Tighten the M11 cylinder head bolts a second pass in sequence to 90 degrees using the J 36660-A .
Tighten the M11 cylinder head bolts (1,2,3,4,5,6,7,8) to 90 degrees and the M11 cylinder head bolts (9 and 10) to 50 degrees a final pass in sequence to using the J 36660-A .
Tighten the M8 cylinder head bolts (11,12,13,14,15) to 30 N·m (22 lb ft). Begin with the center bolt (11) and alternating side-to-side, work outward tightening all of the bolts.
Tighten

Re: Question about head installation

Yes, Tighten all 11mm bolts to 22 ft.lbs.

Turn all 11mm bolts 90 degrees.

Turn all "Long" 11mm bolts an additional 90 degrees.

Turn the 2 "Short" 11mm bolts an additional 50 degrees.

Tighten the top row of 8mm bolts to 22 ft. lbs.
