It’s not that the Gram-Schmidt algorithm fails or is somehow invalid. The problem is that you’ve given it an invalid input: the G-S algorithm is, strictly speaking, only defined for a linearly-independent set of vectors (the columns of the input matrix). The test you’ve been told to use assumes this as well.

For example, in tr[(A⊗1)ρ] the trace is taken over H 1 ⊗H 2, whilst in tr[Aρ 1] it goes only over H 1. It is for this reason that ρ 1 and ρ 2 are called partial traces of ρ, because, in passing from tr[(A⊗1)ρ] to tr[Aρ 1] the trace over H 2 has already been carried out.
