To say *** is putting it mildly

[Saki6]

To say I’m disgusted is putting it mildly.

Is this another way of saying "To put it mildly, I'm disgusted"?

Yes, but I think, to be consistent, it's better written as:

To say I'm disgusted is to put it mildly ( or an understatement).

You'll also hear "I'm disgusted, and that's putting it mildly!"
