Register strides higher than 4 are uncommon but they can happen. For instance, if you have a 64-bit extract_u8 operation, we turn that into UB -> UQ MOV with a source stride of 8. Our previous calculation would try to generate a stride of <32;8,8>:ub which is invalid because the maximum horizontal stride is 4. To solve this problem, we instead use a stride of <8;1,0>. As noted in the comment, this does not work as a destination but that's ok as very few things actually generate that stride.
