I think it's more to do with not everyone wants to go across the water to Newcastle so it gives a service say from Heworth to Heworth / Gateshead and if you change it then it butchers the loop.
If you want the link from Team Valley to Newcastle then imo the better option would be swapping around the 51/52 and 93/94 at the Western side of the route. So the 93/94 go via Dryden Road / Kells Lane direct to Gateshead then continue the usual route around the loop from there to the Queen Vic where it swaps routes with the 51/52 who then takes over the 93/94 from that point and does the Team Valley section around to Gateshead where that side will be extended to Newcastle instead of the other side. They might want to extend the new 93/94 to Wrekenton so it goes down Easedale Gardens and back up Sheriff Hill to keep the Low Fell to Wrekenton link.
It opens up a few new links like Wrekenton and Newcastle to Team Valley and Low Fell to Gateshead College. There's more than enough buses around the 51/52 route to Newcastle.
