Timing diagrams don't always show what happens in the real circuit
(over a long period for example). They are meant to show the timing
relationships between signals. See (10) AC Timing Requirements
as well as the timing diagram. Also (11) Operation

Yes, same as sending MCLR low resets a PIC, but you don't leave it
low or the PIC would be in permanent reset and wouldn't do nuttin'

Sounds about right. The Xck is there to show timing / setup as per (10)

Don't expect to do much on-the-fly image processing with a Stamp BTW.
A bare micro with no interpreter overhead is much much faster
