Hi, I don't think it's the same.
Before update you have the following data [2,"data1", 18] and after update you have [2,"data1", 19]

You can also control this behavior by tuning the binlog_row_image attribute in the config file.

binlog_row_image=full logs all columns which is default

binlog_row_image=minimal logs only changed columns
