Basically, yes. You are playing half notes instead of walking with quarter notes. But it's also a feel thing. I personally think that developing a better 2 feel made my quarter note walking lines feel better. if you can make half notes GROOVE, then you're really cooking. Better yet, if you can make whole notes groove

,... It's also about space. Leaving the right amount of space in any instrument (rhythm section or other) is really important. For my money Steve Gadd is the king of space. Especially the recordings with Gadd and Anthony Jackson (like the Michel Petrucciani trio).
Best resource is just listening to some of the players that other people were posting about earlier. Ray Brown, Ron Carter, any of those old school upright guys. AJ has a great two feel.
I can go on forever about this. I've really come to appreciate and love how simpler bass parts or drum parts just leave the right amount space for everything else, and then still groove like crazy and all of these subtle details just all in to place. It gives room to build the song dynamically. That being said, I still love busy jacoish bass lines as well!!
