A closer look at the numbers.
For the le years 01, 02 and 04.

41-50 / 3-0 (100%)
50+ / N/A
So looking at it, there is obviously a correlation for anything over 20points vs. less than 20 points, but not within these groups. But then of course, as a 2nd banana, Kobe scores more when Shaq is being shut down, no surprises here.
Let's look at the 05-07 years, where Kobe was the undoubted #1 option on Lakers.
Regular Season:
0-10 / 1-1 (50%)
11-20 / 3-12 (20%)
21-30 / 21-23 (48%)
31-40 / 25-27 (48%)
41-50 / 20-12 (63%)
50+ / 4-2 (67%)
Playoffs
0-10 / N/A
11-20 / 1-0 (100%)
21-30 / 2-3 (40%)
31-40 / N/A
41-50 / N/A
50+ / 0-1 (0%)
Not as much or a correlation, in fact, pretty much no effect. So when Kobe is the lead guy, how many points he score doesn't necessarily translates into more wins.
