The diagram you show is not a Trent 1000 so is of course irrelavant to the thread.
The diagram you show has the anti-ice taken off the bleed so is correctly known as bleed air.
The TRENT 1000 does not use BLEED air for the anti-ice.
The reason is that to improve cruise efficiency of the compressor, the bleed valves remain closed. this means there is no air available from the bleeds for anti-ice.
So we put a separate air off take at HP3 on the compressor to feed the anti-air.
Look at your own diagram and then you might understand how the off take on it is from a bleed source and is correctly called bleed air.
But the T1000 does NOT use bleed air for anti-ice and is not the same as the diagram you produce.
