What is being included and excluded when creating a sample contact list with Recipient History?

When I generate a sample list from a larger contact list, I see that one of my options for sample conditions is “Recipient History --> Last Email Invitation Date --> Was Never.” Does this condition mean the recipient has never received an email invitation ever, regardless of what lists the recipient may have been on in the past; or does it only refer to the current contact list? Does that make sense? For example, let’s say I have a contact list called “Big List” with 5,000 people on it, and I’ve created and sent surveys to Sample A with 100 recipients and Sample B with 100 recipients. If I want to create Sample C with unique recipients from A and B, and I choose “Recipient History --> Last Email Invitation Date --> Was Never” as the condition, does that condition only look for the recipients’ history in “Big List” (meaning it would make sure no one from Sample A or Sample B was chosen for Sample C) or does it look at other contact lists I may have used in the past for other surveys? I recognize I can create a sample list and choose conditions to exclude recipients in Sample A and Sample B, but this can become cumbersome if I am dealing with a contact list that has many previous samples that I want to exclude.
