This is not a bug; it is a marked as "by design" by Microsoft. This function is used to know the inserted or updated columns of a table or view. As you may know, each byte has 8 bits so the length of the VARBINARY stream in bytes is the smallest integer greater than, or equal to the number of columns divided by 8. Finally the smallest integer greater than or equal to 3. The bytes of the VARBINARY stream are ordered from left to right, so if you have a table with 15 columns the first byte from the left will contain the bitmask value for columns 1 to 8 the first eight columns.
Then run this test. Even though only col1 is part of the statement the trigger reports that both columns were changed. It will always report that col2 has updated because it is a timestamp column. The test would work the same if col2 was changed to a rowversion. The Update function is much safer and much more explicit when you are troubleshooting.
