I guess it could, theoretically. In the real world, though, it did not.
I'll echo the others who say that the suggestion that Dominik Hasek inflated his save percentage from facing more rebound chances is completely evidence-free, and a major example of the problems of rating goalies subjectively based on their style rather than their results.
First of all, if Hasek created that many extra shots on a regular basis, he would have faced far more shots against than the other goalies he played with. This was not the case.
1990-91: Hasek 28.6, Backups 27.3
1991-92: Hasek 24.4, Backups 25.0
1992-93: Hasek 30.2, Backups 32.0
1993-94: Hasek 27.7, Backups 31.5
1994-95: Hasek 30.3, Backups 28.4
1995-96: Hasek 35.3, Backups 34.7
1996-97: Hasek 32.4, Backups 34.5
1997-98: Hasek 30.6, Backups 31.2
1998-99: Hasek 29.5, Backups 29.2
1999-00: Hasek 27.2, Backups 26.1
2000-01: Hasek 26.5, Backups 27.2
2001-02: Hasek 25.6, Backups 27.0
2003-04: Hasek 23.8, Backups 26.3
2005-06: Hasek 27.9, Backups 28.8
2006-07: Hasek 23.5, Backups 26.0
2007-08: Hasek 21.8, Backups 24.7
The overall average shots faced per 60 minutes are 28.3 for Hasek and 28.1 for his backups. If you weight the backup numbers by Hasek's minutes played in each season, their combined number ends up being 29.7, or 1.4 more than Hasek per 60 minutes. Either way, Hasek did not face a lot of additional shots compared to his teammates, which completely defeats the claim being made about him regularly creating 3 or 4 additional chances at a pop.
Secondly, shots on rebounds are extraordinarily dangerous scoring chances. Read
for a sample of rebound shot data that estimates the shooting percentage of rebound shots in the NHL at around 27%. Hasek's career save percentage was .922, which means that for rebound saves to help his save percentage, opposing shooters would have had to shoot 7.7% or worse on rebound shots. Is it plausible that Hasek was that far ahead of average over his entire career on those types of chances? In my view, even though Hasek was surely the best ever at dealing with those chances, the observed margins in goaltending do not come close to supporting anyone being that far ahead of everyone else.
Thirdly, the number of shots on goal from rebounds in the NHL is actually relatively rare, around 3 for both teams combined per game in the samples I've seen. It can depend a bit on the exact definition of a rebound shot, but it's probably unlikely that Hasek was facing more than 4 rebound shots against in the entire game, much less in the course of one play. Most of the time the defensive team clears the rebound or ties up the opposing team's sticks so they don't get a shot off. And that makes sense, because even with a great goalie in net rebound shots are very likely to go in the net.
From his list and from the discussions, I don't think C1958 was necessarily inconsistent with his rankings, but I do strongly disagree with the relative rankings of different goalie skill sets that informed his votes, because I don't see them as being supportable by the statistical evidence. By far the most important part of goaltending is making the first save, and when you do it as well as Hasek did it (Taco McArthur has him at 80-90 goals above replacement level at his peak), it becomes hard to justify claiming that other skills make up the gap.
