In a typical bathroom floor tile installation you have the following
sequence:

Plywood subfloor, Thin-Set, Backerboard, Thin-Set, Tile/Grout.

If the grout is not perfectly sealed and the bathroom is heavily used

Backerboard is water-damage-resistant, but I hear it can wick and
absorb water. �What are we relying on to keep the water from soaking
the plywood? �Is it just the thin-set?

Water will stop at the lowest point. I don't know how much water
you're talking, but if you have alot, it may get under the baseboard
and flow under the tile and such anyway.

Women are like tile. If you lay them right the first time, you can
walk on them forever. ~~~~it is a joke, for those with no sense of
humor.
