+ <td>When reading a table snapshot, the rows of captured tables will be
filtered using the specified filter expression (AKA a SQL WHERE clause). <br>
+ By default, no filter is applied, meaning the entire table will be
synchronized. <br>
+ A colon (:) separates table name and filter expression, while a
semicolon (;) separate multiple filters,

Review Comment:
How about explicitly stating that the filter conditions are combined using
`AND` and that it has nothing to do with the binlog step?
