I still think they would have the same RPI.

Wrestler A's record is 22-3 for a winning percent of 88% or .880
Let's say Wrestler A's opponents have a combined winning percent of 85% or .850
Let's say Wrestler A's opponents' opponents have a combined winning percent of 90% or .900
Wrestler A has an RPI of (0.25*.880) + (0.5*.850) + (0.25*.900) = .870

Wrestler B's record is 22-3 for a winning percent of 88% or .880
Wrestler B had the same opponents as Wrestler A, who have a combined winning percent of 85% or .850
Wrestler B's opponents' opponents are the same as Wrestler A's opponents' opponents, who have a combined winning percent of 90% or .900
Wrestler B has an RPI of (0.25*.880) + (0.5*.850) + (0.25*.900) = .870

Wrestler A's losses were to better guys (on average) than Wrestler B's losses, but that means A's wins were against worse guys (on average) than Wrestler B's.

It's not very likely that there will be many (or even two) wrestlers with the exact same RPI. The only reason it is the same here is because the two wrestlers had the exact same record and wrestled the exact same number of matches against the exact same guys.
