Matomo import logs multithreading and skip parameter

I have a question regarding the Recorders and skip parameters in the import logs script.
Let assume that I use, 2 recorders, i.e two threads, for example:

t_1 has hits from [0,100]
t_2 has hits from [101,200]

and t_1 fails to record the hits, but t_2 succeeds.
If I use the --skip=0 parameter, it might lead to double imports. Is this a correct assumption?
