it says regarding codec complexity:

high—Specifies two voice channels encoded in the following formats:

G.711a-law, G.711u-law, G.723 Annex A(r5.3),

G.723 Annex A(r6.3), G.723(r5.3), G.723(r6.3),

G.726(r16), G.726(r24), G.726(r32), G.728

G.729(br8), G.729(r8).

medium—Specifies four voice channels encoded in the following formats:

G.711a-law, G.711u-law, G.726(r16),

G.726(r24), G.726(r32), G.729(br8), G.729(r8).

Configuring the codec complexity as medium, blocks the G.723(8) and G.728 voice calls on the voice-card.

So is g.711 and g.729br8 ulaw high or low? how can it be both?

You have an option to run medium complexity codecs as high. So while technically speaking G.711 is by default a medium complexity codec, you can run it as a high complexity codec if you wish.
