Although we've already answered this question via our Ticket Management system, I'm posting the answer here in case it is helpful for others.
The Global Subsets tool only allows setting the x (E-W) and y (N-S) as integers. If you order a subset with x and y as 1km for MOD13Q1, it should result in a subset size of 2.25km x 2.25km with a total of 81 pixels. The 41st pixel (center) will be your 0.25x0.25km subset, and you can retrieve pixels for other subset sizes accordingly. I have attached an example numbering scheme with this email. Please refer to https://modis.ornl.gov/documentation.html#data_format for more information on the data format.
