Random question regarding the rules

A member may be issued either a warning or an infraction if deemed warranted by an admin or mentor (usually from guideline noncompliance). Infractions range from 1 to 10 "points", depending on the severity of the violation; warnings carry no points. If a member accrues 8 or more infraction points, he or she will be automatically banned from Physics Forums for a period of 10 days. If a member receives any infraction after having returned from a temporary ban, that member will then be banned permanently. Obvious, incorrigible spamming or trouble making will be met with a permanent ban.

I was just wondering, wouldn't infractions worth 8, 9, and 10 points be identical from the system's point of view? Chances are, I'm missing something pretty obvious.
