ADV7188 Lock Status In Power Down Mode

In my project i send power down command via i2c (adress 0x0F, data: 0x26) when needed. Datasheet says that i2C is still active on power down mode and i periodically read status information from adress 0x10. But there is something strange. Status byte i read from the chip during power down says that chip has locked to the video (bit 0 indicates IN_LOCK status)(i read 0xCB).

Is this normal or am i doing something wrong?

Or should i ignore the LOCK status during power down?
