Here, I'm starting to be afraid.
Sasuke might have broken the collapse out of respect for Sakura's efforts. He may be an indifferent sociopath who scarcely shows altruistic emotions, but he's not above expressing gratitude or recognition when he feels that someone has earned it.
The "worst case" scenario would be him verbally acknowledging what Sakura contributed to rescue him as he once recognised her determination on the night he abandoned Konoha or the time when he complimented Sakura's genjutsu acuity before the Chunin Exams.
