Storage bin available when posting change is not confirmed completely

Question

Dear Gurus, I have a question for you:
My costumer wants to do a posting change when the material is released from QM with a decision usage from Q to unrestricted use. The process is done in two steps: with LU04 the TO is generated and with LT12 is confirmed. When the TO is generated the position is half confirmed. With LT21 we can see the row for the ST (lets say ST 504 Open Storage type) and a second row 922 TR-ZONE. The first row appears green (as confirmed) and the second row appears red (Not confirmed).
My costumer says that " beacause of the strategy given for the storage entry, the storage bin released in the TO (not confirmed completely yet)   is available at this moment.
If the storage bin is still physically full, the carrier will found not space for leaving the goods even SAP is telling him there is space available at this storage bin."
I have read that once yo start a TO the storage bin is blocked until the transaction is fully confirmed.
If this is correct I need to demostrate it and I don not find the way to do it.
I hope you understand my explanation and give me any clue.
I appreciate very much some help.
Al

From the above it isn't entirly clear that the first part of the T.O. is actualy confirmed, my settings are to autoconfirm this so I have no example to look at in my system. Perhaps the display shows the first line green before any actual confirmation..
I assume the stock status has not changed when you first view the T.O.? If the t.o. is partly confirmed I would expect to see the stock status changed and a neg in 922 until the second part is confirmed. Perhaps there is no confirmation at all yet, in LT21 what is the confirmation status? If you view the transfer order header there would be a partial confirmation showing with a yellow triangle, do you see this or no confirmation indicated at all?
