I think it's helpful to remember there's a pretty strict bureaucratic process in place for everything to do with solving a crime these days. From this site, the government pathologist must declare the manner of death:

I speculate the manner of death for Honey Sherman had been declared (officially signed off) as a homicide and that's why police were putting her name on forms as a victim of homicide.
I assume that means Barry's manner of death had not yet been declared. I don't believe the pathologist had declared it a suicide and closed the file, only to hastily go back and cross out 'suicide' and write in 'homicide' after the word got back about the other autopsy. These are professionals working in a bureaucratic structure, reporting to a chief coroner, etc.
I think it much more likely the pathologist had just not yet filled in the form and signed off on the determination of manner of death, while the homocide squad investigated. There was no urgency, it can wait until the time is right to sign off and hold a press conference. I think in such a high profile case, they'd have preferred to make the public statement strategically, to potentially assist in solving the crime (for eg, releasing CCTV footage), but the family forced their hand.
Instead, they were put on the defensive, explaing they'd been busy doing the incredibly time-consuming job of police work
"Gomes said officers have spent thousands of hours on the investigation so far, including:
The collection of 150 pieces of evidence from the crime scene.
The collection of 2,000 hours of surveillance footage from the area around the Sherman home.
The search of two residential properties owned by the Shermans, including a Miami-area condo.
The execution or orders for 20 judicial authorizations and searches.
Toronto police have searched Barry Sherman's workplace at Apotex Inc., a generic drug manufacturing company that he founded in 1973".
