Mmm... as per "man smartctl", LifeTime(hours) is "(sic) The time at which
the test took place, measured in hours of disk lifetime".

Are both disks "brand new" and "equals" (same manufacturer, same
version), not just "same size"?

If yes, compare the output of "smartctl -A /dev/sd[ab]" and look for
"Power On Hours" values. These, being a raid1, should be similar.
