Pounder, the commentary to section 226.19(c) states: If a consumer accesses an ARM loan application electronically, such as online at a home computer, the creditor must provide the disclosures in electronic form (such as with the application from on its website) in order to meet the requirement to provide disclosures in a timely manner on or with the application. If the creditor instead mailed paper disclosures to the consumer, this requirement would not be met.
I think what the section you referenced it saying is that the disclosure/booklet can either be directly on the application screen, or on another screen linked to it. If the application for an ARM is electronic, then the disclosure/brochure must be in electronic form as well and provided at the same time the application is provided.
