Incorrect solution to IQ test question from Jordan Peterson video?

Question

Shorthand:

Horizontal rectangles called bars, vertical rectangles called poles. Horizontal groupings called rows, vertical groupings called columns.

Ba = Black, Bu = Blue, Y = yellow

Sequence is counted from top-right to bottom-left.

The following patterns are those that could be realized with any of the final shapes put into place:

1. In every column, exactly two poles of the same colour is present.
2. In every column, exactly two bars of the same colour is present.
3. Sequence of colour for bars goes Ba, Ba, Y, Y, Bu, Bu, Ba, ?, Bu
4. Sequence of colour for poles goes Y, Y, Bu, Bu, Ba, Ba, Y, ?, Ba
5. The triangles in every column, row and right-diagonals are all of distinct colours.
6. A yellow pole is always above black bar, a blue bar over a yellow one and a black one over a blue one.

$P(x) =$ number of patterns adhered to by the $x$th option.

$P(1) = 1 + 1 + 0 + 1 + 0 + 0 = 3 \\ P(2) = 0 + 1 + 1 + 0 + 0 + 0 = 2 \\ P(3) = 0 + 0 + 0 + 0 + 1 + 1 = 2 \\ P(4) = 1 + 0 + 0 + 0 + 0 + 0 = 1 \\ P(5) = 1 + 0 + 0 + 0 + 1 + 0 = 2 \\ P(6) = 0 + 1 + 1 + 0 + 0 + 0 = 2 \\ P(7) = 1 + 1 + 0 + 1 + 1 + 0 = 4 \\ P(8) = 1 + 0 + 0 + 0 + 0 + 0 = 1$

The seventh option is the correct one, from what I can tell. The third option didn't even score second. Is it me who is mistaken, the test, or Jordan Peterson (or whoever made his presentation)?

EDIT:

More patterns I've noticed; every triangle on the left-diagonals are of the same colour. Every pole on the left-diagonal are of different colours.

Answer 1

Without watching the source video, and ignoring the options given (so just looking at the grid of symbols as a self-contained PSE puzzle), I see:

Every symbol has an inverted triangle in one of three colours.
So far we have three yellow and three blue.
So I would expect the missing symbol to give us a third black triangle.

Every symbol has one of three combinations of rectangle (blue over yellow, yellow over black, black over blue).
So far we have three "yellow over black" and three "black over blue".
So I would expect the missing symbol to give us a third "blue over yellow" rectangles.

AND every symbol in the grid (so far) is unique.
Adding the missing black triangle with "blue over yellow" rectangles completes the set giving all nine possible combinations.

So I think the answer is pretty clear, but I can understand the unbalanced arrangement of the rectangles being a distraction. There is one of each triangle colour in every row/column, but the rectangles have repeats in some rows/columns but not all, which is ... unsatisfyingly messy.
