As I noted before[1], in Japanese layout terminology, 行頭(line head) 
is the start of line,  頭注(headnote) is placed at the top of page 
in vertical text layout, and 脚注(footnote) is placed at the 
bottom of page. All those are orthogonal to the block-before/after 
directions in Japanese vertical text layout.

I think the CSSWG's 2012-05-30 Resolution,
"RESOLVED: Switch before/after logical directions to head/foot" 
was based on wrong assumption. I found the following discussion 
in the minutes[2]:

   Koji: Footnote appears on the left
   fantasai: And a heading appears on the right side of a section
   <ChrisL> so it is consistent between horizontal and vertical

In Japanese layout terminology, "Footnote appears on the left" is wrong.
Although some text layout softwares (like MS Word) call that "footnote" 
in vertical writing mode, that should be called "sidenote" (傍注) in 
Japanese layout terminology. JLREQ (4.2.6 Processing of Sidenotes in 
Vertical Writing Mode) says "Side notes in vertical writing mode are 
similar to footnotes in horizontal writing mode."[3]

I understand that the term head/foot can be both physical and logical; 
usually same as physical top/bottom, e.g., page-header/footer, 
headnote/footnote, and when the context is given, they can be 
inline direction, e.g., "line-head"(行頭), or block direction,
e.g., "thead" (table-header) and "tfoot" (table-footer).
