Nakamura while being a popular character as always being use as a placeholder for somebody else. Look at his NXT run. He was pretty much a transitional champion on that brand. The problem with Nakamura is that you need to use him as a special attraction for him to stay special like they are doing with Lesnar. By using him on TV every week, he's becoming just another guy on the roster and he's not connected with the casual fans because of it.
Jinder on the other hand, just doesn't work anymore. It's not really his fault because he did improve in the short time he'S been champion. It's more the material they are giving him. So because it's always the same stuff he's becoming stale as a main heel and Champion.
If i was them, i would put the belt on Nakamura at hell in the cell and let him keep the belt until the India tour were you could have jinder win the belt back and if they don't show it on tv, just tape it and present the highlight on smackdown.
In the end, this match hasn't set the world on fire and both character have cool down one because he's on tv every week and doesn't feel special anymore and the other because of creative. But if you switch the title for a little while before continuing the Jinder project, it might give Jinder a chance to breath and practice a little bit before going back as the top guy and Nakamura is a great transitional champion to have.
