Ichigo's behavior was strange, though if he did continue beating Tsukishima, his friends would get in the way. That would not end well.
Something definitely is going on. If I were Ichigo, I'd head to Urahara's shop. There's no way Tsukishima could get to him easily. But I think that Ginjou will have another place to go.
I can just imagine what Orohime said on the phone. (Assuming he actually did call her)
"What are you saying? We met just the other day." Tsukishima
"Oh yeah, you were the guy who attacked me with a sword." Orohime
"hahaha" Tsukishima
