A little more detail for background:
The person who was present in two grids -- the DX operator -- defines their multiple grid location in their side of the TQSL configuration. (The same is true of being in four grids.)
LotW can handle the credit for multiple grids for one QSO.
Section 2.b of "Defining, Modifying, Deleting, or Copying a Station Location" in the TQSL documentation describes it as:
specify the Grid Square in which your station is located (this is particularly important if you operate on VHF or UHF frequencies or via Satellites, as it provides Grid Square credit to your QSO partners pursuing VUCC awards; a Google Maps mashup on which you can click to see your Grid Square is here) The value specified for the Grid Square must be one of the following:
• a valid Grid Square (4 characters) • a valid sub-Square (6 characters) • a comma-separated list of two or four valid Grid Squares or sub-Squares that describe a station location at a Grid Square boundary or 4-way intersection Here's an example of specifying a 4-way intersection:
DM76,DM75,DM86,DM85
