Question about an inbounds pass on the baseline

[South Bay HHVBC]

I think i know the answer, but I am not sure about this. I'll Try my best to describe the situation

Team A commits an inbounding violation by stepping over the baseline underneath team B's basket. Team B is then awarded the ball at that same spot. Now, I know team B is not allowed to run the baseline from this point after the initial infraction by Team A. Player taking the ball out on Team B is shuffling his feet p and down, taking about 8 steps, but all in the same place, basically like his jumping up and down. The referee blows his whistle and calls traveling. I asked him what why he called it traveling and he said because the inbounder took more than 1 step. I was thinking that its one step in either direction from the point of inbounds but with that call, now im unsure. Can someone clarify for me?

Thanks
