You don't need it to be, but some programmers (like mine) want to own Vdd
during programming and will two verify passes, one at each Vdd limit, by
default.  This can be disabled on the command line.  Other programmers may
vary.

The pins needed for programming may be in the datasheet, but programming
details are in a separate document called the programming spec.
