قَامَ زَيْدٌ
Zayd stood up.
زَيْدٌ قَامَ
Zayd stood up, with the subject made prominent at the beginning.
In the second construction, the verbal clause contains a covert pronoun referring back to Zayd. This is one reason the nominal construction can reinforce the attribution. The case of a participle, such as qāʾim, requires separate syntactic consideration: it cannot automatically be treated as identical to a verbal sentence.
The point is to identify the pronoun's referent and the attribution itself before claiming that a judgment has simply been made twice.
