Sending Subject Tests without SAT

I’m pretty sure I’m reading Yale’s score choice policy correctly, but now I’m having second doubts! Yale allows score choicing SAT Subject Tests, so can I choose to only send my ACT and subject tests and not send my SAT I? On one hand Yale says “As long as you provide a complete set of score reports from one testing agency (either the College Board or ACT), you are not required to report scores from both” but on the other hand they say “And if you choose to use a combination of SAT and ACT test results, you must report all scores from both testing agencies.” Are they referring specifically to the SAT I there? Am I worrying for no reason (I’ve already sent them my subject tests and ACT). Thanks!

It’s confusing and was recently debated here -

Thanks!
