Because it always do so, see linux/fs/ext3/super.c:ext3_load_journal():
even if the mount is read-only, the journal is recovered. If (but only
if) the device itself is read-only, then nothing is written back to the
disk. Ext3 clearly lacks xfs' norecovery mount option.

Not mounted rw, but mounted ro with journal recovery.
