This is a simple updating of the Forth 83 definition:
>IN -- addr U,79 "to-in"
The address of a variable which contains the present character offset
within the input stream {{0..the number of characters in the input
stream}}. See: WORD
Which in turn is a simple adoption of the Forth 79 definition:
>IN -- addr U,201
Leave the address of a variable which contains the present character
offset within the input stream {{0…1023}} “to-in”
See: WORD ( ." FIND
So we could say that it has ever been thus.
On the other hand, my copy of FIG Forth (from August 1980) does not contain
a definition of >IN.
