The blue unit is the key here, although the terminology isn't totally
"Independent" has a special meaning from Rule 33, which means "not touching
any [team] equipment].  There's no team equipment in the third picture, so
that's not an issue.

For people who think that there are 7 levels from the white/tan/blue units,
note that the blue unit does not form a stack 1 level high.  To be
considered a Stack, a collection of building units must have Level 1
touching Flat Down on the Mat, and the blue unit isn't touching the Mat.
A Stack also has any higher levels touching Flat Down on the level below.
In the third picture, the blue unit is touching Flat Down on both the Level
3 Tan and White units. The blue unit is Level 4 whether you travel up the
white side, or travel up the tan side.  Because it touches Flat Down on
both, the whole collection of white/tan/blue is a single Stack of height 4.

It does take a lot of staring and thinking to understand the Mission 12
scoring, so these are good questions.
