Alternating rectilinear hoops 1

Hello all, I cannot find and hopefully it doesn't exist.....

Are the 135 degree hooks on rectilinear hoops required to be alternated from one corner of a column/pedestal to another? I've seen it both ways: All hooks on one longitudinal bar and rotated as mentioned. I'm being challenged by a client QA who I believe has misinterpreted the following:

7.10.5.3 — Ties shall be arranged such that every
corner and alternate longitudinal bar shall have lateral
support provided by the corner of a tie with an
included angle of not more than 135 degrees and no
bar shall be farther than 6 in. clear on each side along
the tie from such a laterally supported bar. Where
longitudinal bars are located around the perimeter of a
circle, a complete circular tie shall be permitted.

Any help would be greatly appreciated.

135 degree hooks of a closed tie do not need to be alternated.
Crossties consisting of a 90 and 135 degree hook need to be alternated sides along the height of a vertical bar that it's confining.
