No it doesn't, Danielle
When the volunteers did the graveyard survey, they assigned their own numbers to each headstone, ignoring any plots without any sort of stone or memorial. Consecutively numbered MIs could have any number of unmarked graves between them. They also divided the graveyard into several sections and started numbering at 1 in each section -- so you have A1, B1, C1 etc.
The numbers they assigned have no relation to any official plot number in the church books
