A quick check of 93's ROM confirms it is the same there, as well as 95 (they're flip flopped in 96). I wonder if their abbreviations (WPG and WSH) have something to do with it. Same oddities also apply to the SNES versions of 93 and 94 and the Sega CD version of 94.
A couple similar oddities I noticed:
Dallas' data is still between LA's and Montreal's in 95 and 96 (it's in the correct spot in 97 and 98). Strangely, Anaheim and Florida's data were moved to the correct spots (before Boston and between Edmonton and Hartford, respectively), though. Weird that they'd move them but not Dallas.
In 97 and 98, both Colorado's and Phoenix's data are in the proper spots (between Chicago/Dallas and Philadelphia/Pittsburgh, respectively) following their respective relocations, yet in 98, Carolina's data is between Florida's and LA's, an obvious remnant of their relocation.
