Hmm.  These are the same people that once published a app note for sensing
AC line voltage by tying it to a PIC pin via a large resistor.  Microchip
datasheets are very good and the limits listed in them should be carefully
followed.  However, I wouldn't look to Microchip for good design advice
beyond that.  I've seen too many irresponsible or downright bad examples.

If you can find a reason for tying the resistors to ground via a resistor
from the datasheet specs, then you've got my attention.  Otherwise, this is
likely mere superstition by whoever wrote that document.
