What about an inline-level element with a display value of block? An 
inline-level element is not a block-level element so saying boxes covers 
both situations.

I think it means that the used value for position is static.

What information?

No, the part you quote says adjacent. This is describing a adjacent 
sibling elements, not adjacent as in adjacent margins between a parent 
and child element.

No, the box can be block-level with line boxes. It is the line boxes 
that may shorten (the spec has shrink).

9.5.2 is title "Controlling flow next to floats". Doesn't that exclude 
absolutely positioned elements?

The reason why you see mention of absolutely positioned in 9.5.1 is that 
boxes that have both float: left and position: absolute declared on them 
are only absolutely positioned and the use value for float is none.

I think "and solve for that value" is sloppy but it is a value for 
either bottom/top/left/right.
