A cup of water you filled befor to rinse your mouth after brushing.
I would guess that you “need the water while brushing” because they spit into the sink and to wash that away immediately instead of rinsing the sink and spit out toothpaste foam after finishing brushing.
Not something I do but I could imagine people being particular about it for some reason.

You aren’t supposed to rinse your mouth after brushing, so even that is bizarre.
