Impedance Matching Confusion

My stereo amplifier has two sets of binding posts for each channel. The user manual says that it can drive a pair of 4 ohm speakers if only one set of the binding posts are being used. If I were to use both sets of binding posts, it can drive speakers that are between 8 ohm to 16 ohm. My speakers are rated at 4 ohm and they support bi-wiring. My question is that if I use both sets of the binding posts on my amplifier to bi-wire a pair of 4 ohm speakers, will it cause any issue/damage? Thanks.

My amplifier’s Power Output: 200 W + 200 W (8 Ω) 400 W + 400 W (4 Ω) / The speakers are rated at 4 ohm with 90db sensitivity.
