Here the explanation of 3♦ is criminally reticent in terms of both strength and length of fit: is the fit "9 trump" as explained (no) or "The law" (yes, but that is 10 trump) or 2+ as stated (insert comment).
The successive explanation of 4♦ is more bashful about length but equally reticent in terms of strength.

Standard case of GIB being unable to display 'or' in descriptions. 3♦ is:
3 diamonds and 4-16 total points, write law in the description (from the LOTT rule)
or
2+ diamonds and 14-17 total points (from a generic rule about making a non-jump bid at the 3 level when LHO has bid something)
Combining both descriptions gives the result.
In this case it's the second rule firing; if West passes or North has one less point, it triggers a different rule about bidding 4♦ based on LOTT.
