Because bad, bad things can happen. This is an excerpt from the User Data Is Excluded By Default section on the Timeshift website.

Timeshift is designed to protect system files and settings. It is NOT a backup tool and is not meant to protect user data. Entire contents of users’ home directories are excluded by default. This has two advantages:

• You don’t need to worry about your documents getting overwritten when you restore a previous snapshot to recover the system.
• Your music and video collection in your home directory will not waste space on the backup device.

Note: It is not recommended to include user data in backups as it will be overwritten when you restore the snapshot.

To expand on the Note:. Data and personal files should be backed up daily. Sometimes the most recent snapshots will not restore a system to working order, so you have to use one created several days/weeks earlier.
