This actually seems like just a very clever market segmentation solution since the GPU was already limited to 8x PCIe lanes (its a laptop GPU see https://www.notebookcheck.net/NVIDIA-GeForce-RTX-4060-Laptop...). The 'addition' of the M.2 SSD makes it a unique offering. Limiting it to only one drive is another way to keep the thermal envelope down. Kudos to the Asus design and product development folks.

Most desktop class boards can only support bifurcating a 16x lane slot into two 8x lane slots, so it's more about preventing user error, as 2 M.2 slots would likely not function in most cases.

Even on server class hardware, the split options for a single slot are usually (but not always) 16x, 2* 8x, and 4* 4x - an 8x + 2* 4x option is somewhat unusual.
