Correct usage of note bars in the 'Repetion of a single note or chord' section - a question

In bars number 1 to 4 of the graphic example score, each note bar in the written note is expressed as notes containing that same number of (barring part of note) bars. For bar 1, a 1/2 note with one single note bar becomes a series of 1/8th notes (ie. a note with a single bar in the barring section, per the number of bars in the written note). Similarly, in bar 2 a full (length = 1) written note with 2 note bars is expressed as a 1/16th (2 bars) note ie. the played note's bar count matches the number of written note bars (2).

However, in score bars 5 and 6 there's are slightly different potential interprations. The first interpration is that the played number of note bars matches the number of note bars in the written muscial bar, including the extra bar of the written note iteself. The second interpration is that the number of bars determines how many times the note is halved, so for 2 note bars you would divide the note lenth by 8 (1/2 x 1/2 * 1/2). Two exakl[e bar 5, a 1/8th note with 1 note bar is played as a series of 1/16th note 1/8 divided by 2). Similarly in bar 6, a 1/8th note with 2 note bars becomes a 1/32 note (1/2 x 1/2 x 1/2) * 1/8'. The end result of the two interpretaion are the same however, so, Unless I've missed something, or there's a musical custom going on, it looks like an inconsistency.

I've formulated a rule that covers all examples in the score graphic a bit more simply: When a score has a note with a 'bar' in it, play the note faster by doubling it as many times as there are bars including both stroke bars on the note, and the the bar in the barring section of the note.

Perhaps a music notation (musicologist) expert can comment - what's the correct interpration of bars on note?
