Here you are calling Date.today with -1 as the first parameter. (Check the doc., it takes an optional parameter.) You could have equivalently written Date.today(-1). That parameter doesn't do anything relevant in this case (In fact, I'm not clear on its function.), so you get today's date.

Here you are subtracting 1 from today, so you get yesterday.

No surprise here.
