I don't think anyone has ever studied these nearly enough to answer your question. However, the number on the player piece does correspond with the number at the bottom of the label. My thinking is that the label is the important part--it would be less than ideal if a right fielder piece was attached to a pitcher pose but once the label is on the player piece you can no longer see the number underneath.
Keep in mind these were reissued each year and a particular player could be found in different "poses" (especially the pitchers--as each team had a few. But say for example Heilmann played in 1922 as rght field and switched to center field the next year, they may switch his player pose to correspond to with Heilmann. Each team was styled differently--even though the same generic poses were used--so they aren't totally generic in regards to the team.
I've never looked into the cards that closely but if all "right fielders" were always given the same pose and that is different than the one that the Heilman card w/ label you show has then it was probably a mistake. But also keep in mind that in the 1922 team set Heilmann may have been #14 in that set but in 1924 he may have had a different # on the sheet--so I would use some caution making assumptions until more info is gathered.
