I don't think so. The exact text:

         Some systems only permit the use of blocks consisting of
seven-bit, printable text.

It does not say base64 is 7bit, just that those teletypes at the time (like
the ADM-3 "egg" terminal I used in University), only supported 7bit
printable text, and so could not do 8bit raw text, and so we have to use an
encoding (which is a base64 one which uses 6 bit printable characters only).

Similarly in the other bit (pun intended) text:

       Either of these alternatives may be ASCII-armored (see Section 6.2
if they need to be transmitted across a text-only (or 7-bit clean) channel.
