There are several problems with this.
1. The modern cover is (almost certainly) not the one that it had when Marci sent the book.
2. The inside cover we see now is (also almost certainly) not how it was when Voynich received the MS.
There must have been a paper pastedown, and some stuffing. Voynich was known (already in 1908 - before he got the Jesuit manuscripts) to remove these and check the contents for 'hidden treasures'. He found quite a few such treasures.
Here is an example from the same collection, that did not pass through Voynich's hands, that shows how the MS would have looked when Voynich first got it:

Remnants of what Voynich tore off are still visible, and these do not seem to be from the Marci letter.
The pencilled J1022, Voynich's catalogue number, was written on top of these remnants.
There are several different ways how to fill in the missing steps. The orange marks on the inside of the cover are a bit hard to explain, as there would have been stuffing there. Unless some item with wax was part of the stuffing. Perhaps even the Marci letter itself? That is not impossible, but seems unlikely. Or the marks came after the pastedown and stuffing were removed?
Here are two examples of how Marci folded some of his other letters to Kircher (from APUG 557, f65 and f124).
We can't be sure, but if Marci folded the letter like this, and then either he changed his mind, or a a later owner refolded it to fit onto the front cover, we seem to get roughly what the letter looks like now.
The precise purpose of the wax seals on the letter remain unclear and may also be the result of two events.
