Drop Box eligibility for B1/B2

hi all

Can you please help me for the following question for Drop Box Eligibility criteria for B1/B2 ?

My mom already have B1/B2 visa stamp on the passport which expires on Nov 2023.

During scheduling appt for visa renewal I see the following question:

Have you ever been refused a B1/B2 visa before?

Does it mean since the last visa issuance ?

or

Does it mean anytime before the last visa issuance ?

What will be the answer for this scenario for the above question ?

If the applicant has ever been refused a visa, it was for the same visa class for which they are currently applying, and they were subsequently issued that class of visa.

Can you please help me to understand this as it is stopping me to go forward without knowing the actual intent of this question ?

Thank You
