Why is the speech signal not convolutional mixing

Hello, fakufaku, thanks for your amazing work!
I have just started exploring BSS and I have a question. Why is the signal not convolutional mixed?
It seems like linear mixed. Isn't this contradictory to the theory of IVA? IVA requires convolutional mixing in the time domain and linear mixing in the frequency domain.
this is the mixing code:

auxiva-ipa/room_builder.py

Line 198 in ec9d17c

mix = np.sum(premix[:n_tgt, :], axis=0) + bg + un

I have been troubled by this issue for a long time. You are an expert in this field, can you give me some advices?
