Honestly, this is an area the book is very much lacking.

In any other rule, if there is a term that is important to the enforcement of the rule, you can find that term defined in rule 1. "Infielder" is very vague. Every umpire's interpretation of the rule is going to differ on this one, and that's something we don't want.

Mike has hinted at one way some umpires would interpret it. I've come across some crazy ones.

Question for Mike - would you allow the following:

F3 (female) and F5 (male) playing inside the baseline about 2 steps.
F4 (female) and F6 (male) playing on the outfield grass about 10 yards.
F7 (female) and F10 (male) playing very near the foul lines, perhaps 5 yards deeper than F4 and F6.
F8 (male) and F9 (female) playing almost at the warning track, spread further wide than F4 and F6.

A local team used to line up this way. Some umpires would allow it, some not... they would invariably complain until they got their way, and then some UIC's would allow it, some not. Then some TD's yes, some no.

Biggest problem for me on this alignment was that they had, to my mind, 6 infielders, and while F10 was not closer to first base than F3 ... F10 could definitely make plays there, especially if the ball was hit to F1 or F5 (and moreso if the runner was slow).

Sometimes when someone argued the 6 infielder angle, they would move F4 and F6 back to be deeper than F7 and 10. Essentially all 4 "infielders" were on the foul lines, and all 4 "outfielders" closest to second base.

Sounds wonky - but they would shift around a lot based on the hitters, so defining who was what, exactly, for any given hitter was a nebulous thing.
