It seems that the former form may also depend on udev having settled.
--8<-- mount(8)
The device indication.

The recommended setup is to use tags (e.g. LABEL=<label>) rather
than /dev/disk/by-{label,uuid,partuuid,partlabel} udev symlinks
in the /etc/fstab file. The tags are more readable, robust and
portable. The mount(8) command internally uses udev symlinks, so
use the symlinks in /etc/fstab has no advantage over the tags.
For more details see libblkid(3).

Oops. Let's look further:
--8<-- libblkid(3)
The high-level part of the library supports two methods to evaluate
LABEL/UUID. It reads information directly from a block device or read
information from /dev/disk/by-* udev symlinks. The udev is preferred
method by default.

..so when is the non-default method (querying devices) used?
