"Right--we don't know which way Orange went anyway. We'll just get lost."

Taiki was right. There wasn't any use on trying to catch up and finding someone this far on. Tidus picks his pace back up, to continue going forward with Taiki.

"We'll trust the people with us. If we need anyone else... Spider can help. She'll be over there. We'll bring someone over that way."

Actually--that was way easier, wasn't it? Especially with how far the dot from their landing point and to the station appeared to be.
