Nope it does not contradict any of it:
Federal Register - BIS EAR - Encryption Export Control Regulations.
There are plenty of details about key length restrictions for export control.
You quoted the relevant sentence yourself:
Most encryption products can be exported to most destinations under license exception ENC, once the exporter has complied with applicable reporting and classification requirements
If you really want to learn about US crypto export control details, you need to spend a lot of time reading the Federal Register, because these regulations are spread around many documents.
