Johnson remote control cams - different part numbers for 20" and 25" motors?

I was looking in the parts breakdown for my motor on the evinrude site and I noticed the shift / throttle cam in the remote has two different part number designations for 20" (pn 0389266) and 25" (pn 0397272) motors. does anybody know why it matters?

I thought the only difference between the motors was a longer midsection (and associated parts) so why would the cam in the remote be different? Does this also mean that remote controls of similar type are NOT blindly interchangeable?

Thanks!
