Why is P21w used from online parts to describe proper yaris bulb(reverse)

UPDATE: from a quick search

(1156 is a single filament bulb. P21W I can see being used to reference both 1156 and 1157 (dual filament) bulbs)

Just ordered these.

Same company and seller that I got my rear red running/break led and are really much brighter the stock.
