putting plywood underlayment for shower, does it have to be 1 piece?

i'm putting in a 11/32" plywood underlayment on top of 3/4" subfloor for a 3' x 5' shower

i had a brain fart screwed in a piece of 3' x 4' underlayment already and realized there's a 1' x 3' gap. how bad is this? i'm just putting on schluter shower pan on top. will this be an issue and should i redo it and put in 1 piece of 3'x 5'? or is 3' x 4' + 3' x 1' fine? thanks!


i'm also planning on putting in self-leveling compound, will it matter?
