'See him told' versus 'See that he is told'

OP's first example is probably intended to mean...

1: What I always see is that he is told to do the same thing.
...or more accurately,...
2: What I see is that he is always told to do the same thing.

Ignoring that ambiguity about the intended referent of always, there's a completely different meaning that's more likely to be conveyed by OP's second example...

3: I always see to it that he is told to do the same thing.
...or more accurately,...
4: I see to it / make sure that he is always told to do the same thing.

Note that these are just likely intended meanings. In principle, either of OP's versions could validly be used with either sense.
