When accepting a quote with split invoices, invoice notification for one or both?

[websavers]

When you've had a client accept a quote and you're in the process of converting it to invoices, WHMCS provides the option to Split into 2 invoices - a deposit and final payment. Below that it says "Send Invoice Notification Email".

If you check that box to send the invoice notification email and click Submit, will it:

1. Send an invoice notification for both invoices (when you've gone with split invoices)? Or

2. Send an invoice notification email for just the first invoice?

Does anyone know the answer?

Documentation on this is here, but does not have the answer to that question.
