That seems to be mere happenstance. Using ext3 vs ext4 likely just slightly alters the exact IO pattern to cause a different number of md events. As long as the md event counter is not the same then adding the second modified disk back in causes a resync, destroying the changes specific to the second disk and going with the changes on the first detected disk.
