Max value greater than min value

I got the sharding mongodb status like below,the max “temptime” greater than min value, is that normal? Thanks.
min: {
tmno: ‘66084779’,
temptime: 1701262170000
},
max: {
tmno: ‘66084835’,
temptime: 1683280050000
},
‘on shard’: ‘shard2’,
‘last modified’: Timestamp({ t: 1, i: 25 })

Yes that is normal as the shard key is using a compound index.

This index(and key range) is primarily ordered on tmno then on temptime
