And this is relevant to ext4... exactly how?

One nice thing with ext4 is that fsck times are reduced (typically) by a factor of 7-12 times. So a TB file system that previously took 20-25 minutes might now only take 2-3 minutes.
That is the case only for fully undamaged filesystems, that is the common case of a periodic filesystem check. I have never seen any reports that the new 'e2fsck' is faster on damaged filesystems too. And since a damaged 1.5TB 'ext3' filesystem was reported take 2 months to 'fsck', even a factor of 10 is not going to help a lot.
