Your link does not support that claim. However, that same website refutes it in another article. See Hamilton and the British Plan.
From the link I sent you.
1. Like the final draft, as found at Article 1, Section 1, Hamilton’s plan included a bicameral legislature. Hamilton envisioned that each house would have an active “negative” on each other, while the system in the final draft is more passive.
2. Similar to the final draft’s Article 1, Section 2, Hamilton’s Assembly was elected by the people, though for three year terms.
3. Hamilton’s Senate was elected for life from districts rather than from the states. The method of indirect election is similar to the Electoral College defined in Article 2, Section 1 of the final draft.
4. Again predicting the Electoral College, Hamilton’s executive, the Governor, was elected for life, by the Senatorial electoral districts. He had a veto, as found at Article 1, Section 7. He also would have been commander-in-chief of the military, would have negotiated treaties, appointed his own cabinet officers, and had the pardon power, powers vested in the President by Article 2, Section 2.
5. Instead of a fixed line of succession, as found at Article 2, Section 1, Hamilton’s Governor would be replaced by a temporary Governor appointed by the Senate until a new Governor was elected.
6. Except for the power to declare war, which was granted to the Congress as a whole in Article 1, Section 8, Hamilton’s Senate had some of the same powers as that of the final draft.
7. Hamilton’s unnamed judicial branch had a dearth of original jurisdiction, but shared the life term of the final draft’s justices as found at Article 3, Section 1.
8. Hamilton’s draft gave his legislature the power to constitute lower courts within the states, just as the final draft does in Article 3, Section 1.
9. Hamilton’s plan includes a lengthy section about impeachment, and includes most of the details found in the final draft at Article 1, Section 2 and Section 3 and Article 2, Section 4.
10. Hamilton’s plan took the supremacy concept a few steps further than the Supremacy Clause, at Article 6, by allowing the national government to veto any state law and by mandating the veto power and appointment method of state governors.
11. Hamilton’s plan again went beyond the final draft by not only mandating that the states not keep armies or navies, as at Article 1, Section 10, but also gave the national government power over the state militias.
Madison's, Virginia plan gave national veto power over any state legislation.
Paterson's New Jersey plan had laws set by congress taking presidence over state laws.
Pickney's plan also gave national veto power over stated legislation.
