Epriton mineral fields not mining like a proper liquid ore

As i understand it when mining a liquid ore the field is supposed to deplete from the edges like it is evaporating. Experimentation with this while mining epriton has yielded a strange result. what currently seems to be happening is:

1- from the tile you are mining run a straight line to the north west untill you hit the edge of the mineral field
2- start depleting there
3- follow the line back to the targeted tile depleting squares as you go untill you reach the tile being mined
4- report tile as out of minerals.

i have not tested this on either hdt or liquizit so i dont know if this applies to all liquid ores or just epriton

Tile scans and screen shots.

image is a little big it is a series of 3 screens shown in sequence

edit* tested HDT and Liquizit both exhibit the same behavior
