Why should I keep my emergency fund separate from my sinking funds?

Because they answer two different questions. An emergency fund covers the unexpected — job loss, a sudden medical bill, a surprise repair — and you hope to never touch it. A sinking fund is money you deliberately set aside for a known, planned expense — a vacation, holiday gifts, annual insurance premiums, a new roof you know is coming — by saving a little each month until the bill arrives. If you blend them, you'll dip into the safety net for predictable costs and convince yourself you're "fine," leaving nothing for a real emergency. Keeping them in separate buckets (separate accounts or labeled sub-accounts) preserves the emergency fund's purpose and makes your budget honest.
