I think you have to very careful moving checkers around. It matters very little what you do on the far side of the board (White's in the original post, or Brunette's in the rollout post), but it can make a big difference on the near side where the action is.
Even moving back a 6pt spare back to the 8pt has a substantial impact, because it represents an extra 6 in some variations (also double 3s to fill in the 5pt) and in any case it's 2 more pips to play with, before the near-side player must break a point: this helps the stiff 10pt position significantly more than the fluid non-10pt position. And moving a spare from the 6pt to 7pt (only one pip but it can still gain a 6) has an an even greater impact because its presence bails out the stiff 10pt position when a 32 or 21 is rolled (making the 5pt).
Matt said much the same thing, but perhaps the above rephrasing and expansion will help.
As I stated in my related post today (in response to Keene), it is important to realize that the 10pt is a liability safety-wise, otherwise it is impossible to understand the nature of the tradeoff -- why making the 10pt is right in the actual position, but it starts to become wrong when your lead increases by an additional 5 pips or so.
