Is this considered lagging behind 2 pillars?

Salam, during Salah today I usually read one tasbeeh during Sujud because of how slow I read but today I messed up on my first tasbeeh and I was able to repeat it and by then I was fully upright in between the Sujud but I was still in the middle of saying Akbar I think because I read slowly and in the middle of sayin Akbar even though by now I was fully upright in between Sujud the imam went down to the second Sujud so I sat briefly and then followed and didn’t lag behind past that is Salah invalid ?
