Gentleman,
There is a theory among course operators that cart paths SHOULD cross fairways beyond the landing area, as it makes them more accessible and tends to speed play.
Art may or may not have laid those out, but whoever did simply gave the management company what they wanted.
It is possible to hide these from the play line of view with a small ridge. Granted, you see them from the green looking back in most cases. That might not be evident from the yardage books.
The downside to that theory, even if they are made invisible is that a path out of play when built might be very much in play a few years later.
