I would say it's more complicated than that. They launched without Touch because they needed to (already some content lined up for xbox controller, plus wanting to beat Vive to market, plus wanting to put more polish on the controllers). The headset itself could do 360 itself just fine. But people took that to mean that Touch in the future wouldn't be room scale and so that resulted in more misinformation. 

Then the controllers finally came out and they started with a default software setup of two front sensors, but you could actually set them up on opposing sides to get 360. It's just that the software didn't tell you it was supported. Later on, they added software support to label that setup as an actual setup you could do, and the experience itself was also a bit better. 

Btw a past article I found if you want to confirm the timeline here.
