Probably because you can't :-)

But you can get around it by explicitly assigning a value to the
field when you update the row, e.g

   UPDATE myTable SET tsCol = tsCol, foo = 'bar' WHERE...

On the other hand, if you don't want TIMESTAMP behavior from a
TIMESTAMP column, maybe you should just change it to a DATETIME :-)
