Why do the parameters of lists commands ask for int64 instead of int32?

While I was using go-redis as library for connecting to Redis I used to convert most of my integers from 32 bits to 64 bits due to the parameters type of list commands:

go-redis/list_commands.go

Lines 26 to 29 in 8b15101

	LRange(ctx context.Context, key string, start, stop int64) *StringSliceCmd
	LRem(ctx context.Context, key string, count int64, value interface{}) *IntCmd
	LSet(ctx context.Context, key string, index int64, value interface{}) *StatusCmd
	LTrim(ctx context.Context, key string, start, stop int64) *StatusCmd

However, I noticed the limits of Redis is mostly based on integers within a range of 32 bits, so why does it need to be 64?
